It fails in the buyer&#8217;s specification, three weeks earlier, when nobody wrote down what the door has to survive. We manufacture industrial doors in Hebei and ship to more than 70 countries, so we read enquiries from the other side of the table. The enquiries that turn into good projects ask uncomfortable questions; the ones that turn into disputes ask none.<\/p>\n<p>The five questions below work in that order. You answer each one for your own opening first, then you make the supplier answer it in writing. Keep the category wording honest while you do it: our guide to <a href=\"https:\/\/www.raxdoors.com\/blog\/what-features-make-an-industrial-door\/\">what features make an industrial door<\/a> lists the six features a spec should name. That two-sided habit is what separates the useful questions when specifying an industrial door from a checklist that just gets attached to an email. Have not picked a door type yet? Start with our guide to <a href=\"https:\/\/www.raxdoors.com\/blog\/selecting-industrial-door-solution\/\">what to consider when selecting an industrial door<\/a>, then come back for the commercial interrogation.<\/p>\n<p>After working through these questions, the building-level matching guide on <a href=\"https:\/\/www.raxdoors.com\/blog\/choosing-industrial-door-systems-premises\/\">industrial door systems for your premises<\/a> shows how each answer shifts the system shortlist.<\/p>\n<figure><img decoding=\"async\" src=\"https:\/\/www.raxdoors.com\/wp-content\/uploads\/2026\/08\/industrial-door-category.jpg\" alt=\"Industrial door range laid out by category for a specification meeting\" width=\"1120\" height=\"680\" class=\"wp-image-1455\" loading=\"lazy\"><figcaption>Specifications come before catalogue pages, not after<\/figcaption><\/figure>\n<h2 id=\"vague-quotes-start-with-vague-specifications\">Vague Quotes Start With Vague Specifications<\/h2>\n<p>Put three quotations side by side and most cannot be compared. One prices the door leaf only, one adds a motor, and one quietly assumes somebody else will install it. Each supplier answered a different brief, and none of them is lying. A tender specification exists to make bids comparable.<\/p>\n<p>The five questions when specifying an industrial door that force comparable answers fit on one page. Two of them you must answer honestly before contacting anyone. Three of them exist mostly because suppliers have learned to stay silent where buyers stay vague.<\/p>\n<h2 id=\"how-many-trucks-cross-this-opening-at-peak\">How Many Trucks Cross This Opening at Peak<\/h2>\n<p>Every door has two traffic numbers: the quiet Tuesday and the worst hour of the week. Only the second sizes the door. A food plant that runs forty forklift movements through a chill-room opening before ten needs hardware built for that spike. Count the forklift trips for one real peak shift before writing anything down.<\/p>\n<figure><img decoding=\"async\" src=\"https:\/\/www.raxdoors.com\/wp-content\/uploads\/2026\/09\/stock-5-questions-specifying-industrial-door-cand_02.webp\" alt=\"Red trailer truck waiting at a warehouse loading dock during the peak shift\" width=\"1200\" height=\"799\" class=\"wp-image-4319\" loading=\"lazy\" srcset=\"https:\/\/www.raxdoors.com\/wp-content\/uploads\/2026\/09\/stock-5-questions-specifying-industrial-door-cand_02.webp 1200w, https:\/\/www.raxdoors.com\/wp-content\/uploads\/2026\/09\/stock-5-questions-specifying-industrial-door-cand_02-300x200.webp 300w, https:\/\/www.raxdoors.com\/wp-content\/uploads\/2026\/09\/stock-5-questions-specifying-industrial-door-cand_02-1024x682.webp 1024w, https:\/\/www.raxdoors.com\/wp-content\/uploads\/2026\/09\/stock-5-questions-specifying-industrial-door-cand_02-768x511.webp 768w, https:\/\/www.raxdoors.com\/wp-content\/uploads\/2026\/09\/stock-5-questions-specifying-industrial-door-cand_02-18x12.webp 18w\" sizes=\"auto, (max-width: 1200px) 100vw, 1200px\" \/><figcaption>Peak hour, not average day, decides the door class<\/figcaption><\/figure>\n<h3>Why the Traffic Question Gets Dodged<\/h3>\n<p>Suppliers quote by door family because the catalogue is already written. Asking you to count cycles costs them a day and risks quoting a cheaper door than their competitor will. A class rating also travels better in an email than an honest sentence about your Tuesday shift.<\/p>\n<h3>What a Counted Answer Looks Like<\/h3>\n<p>A qualified supplier converts your counted peak movements into hardware language: a spring cycle rating, a door speed band, a motor duty grade. Our sectional springs, for example, are specified for at least 30,000 cycles. Our high-speed range runs 0.8 to 2.5 m\/s for openings that never stop. An answer with no numbers and no assumptions is a catalogue page, not a specification.<\/p>\n<h2 id=\"does-the-quote-cover-installation-and-acceptance\">Does the Quote Cover Installation and Acceptance<\/h2>\n<p>Supply-only and turnkey are different products wearing the same word: quote. Comparing them is like comparing an engine with a drivetrain; one turns over, the other moves the truck. A supply-only price ends at the port, the default for manufacturers like us who ship FOB Tianjin or Qingdao without crews abroad. Your local contractor then owns the mounting, the wiring, and the handover. That division works only when both parties wrote it down before the order.<\/p>\n<div class=\"callout\">\n<p><strong>Watch point:<\/strong> acceptance is where scope disputes surface. Agree in advance what a finished installation must demonstrate: rated speed, safe reversal, sealing, and a signed test record.<\/p>\n<\/div>\n<h3>Why Scope Stays Fuzzy on Paper<\/h3>\n<p>Scope stays vague because vagueness wins jobs. The thin quote looks cheaper in a comparison table, and the missing line items resurface as variations after the award. Safety guidance on work equipment, such as <a href=\"https:\/\/www.hse.gov.uk\/work-equipment-machinery\/\" target=\"_blank\" rel=\"noopener\">the UK HSE framework<\/a>, runs on the same principle: someone must own every duty, in writing, before the equipment arrives.<\/p>\n<h3>What a Complete Quote Lists<\/h3>\n<p>A complete offer itemises three things: what is supplied, what the buyer arranges locally, and which documents prove conformity. Ours include factory inspection records for speed, noise, and insulation resistance, a first-article sample sign-off, manuals with CAD drawings, and the CE declaration under EN 13241. Where fire compliance matters, ask how a <a href=\"https:\/\/www.raxdoors.com\/industrial-doors\/fire-rated-industrial-steel-door\/\">fire rated industrial steel door<\/a> will be verified for your project. An EI rating claimed without project-specific test evidence is a brochure, not a certificate.<\/p>\n<h2 id=\"how-will-delivery-fit-the-changeover-window\">How Will Delivery Fit the Changeover Window<\/h2>\n<p>A door that arrives before its opening is ready does not wait for free. On one refit we heard about, the door reached the site while the civil team was still pouring the approach slab, and the crane contractor had already demobilised. The changeover window, meaning the hours a live facility can lose an opening, is your number to state. Suppliers cannot respect a deadline you never named.<\/p>\n<figure><img decoding=\"async\" src=\"https:\/\/www.raxdoors.com\/wp-content\/uploads\/2026\/09\/stock-5-questions-specifying-industrial-door-cand_05.webp\" alt=\"Industrial loading dock with closed bay doors awaiting changeover\" width=\"1200\" height=\"799\" class=\"wp-image-4320\" loading=\"lazy\" srcset=\"https:\/\/www.raxdoors.com\/wp-content\/uploads\/2026\/09\/stock-5-questions-specifying-industrial-door-cand_05.webp 1200w, https:\/\/www.raxdoors.com\/wp-content\/uploads\/2026\/09\/stock-5-questions-specifying-industrial-door-cand_05-300x200.webp 300w, https:\/\/www.raxdoors.com\/wp-content\/uploads\/2026\/09\/stock-5-questions-specifying-industrial-door-cand_05-1024x682.webp 1024w, https:\/\/www.raxdoors.com\/wp-content\/uploads\/2026\/09\/stock-5-questions-specifying-industrial-door-cand_05-768x511.webp 768w, https:\/\/www.raxdoors.com\/wp-content\/uploads\/2026\/09\/stock-5-questions-specifying-industrial-door-cand_05-18x12.webp 18w\" sizes=\"auto, (max-width: 1200px) 100vw, 1200px\" \/><figcaption>Sequence the openings so the site never loses more than it can spare<\/figcaption><\/figure>\n<h3>Why Lead Times Slip Quietly<\/h3>\n<p>Lead times slip because production is only one leg of the journey. Sampling, ocean transit, customs, and site readiness all add days, and only the first two belong to the factory. A buyer who hears &#8220;twenty to thirty-five days&#8221; and writes nothing else into the plan has accepted one leg as the whole journey.<\/p>\n<h3>What a Delivery Plan Includes<\/h3>\n<p>A qualified answer sequences the job. Our standard lead times run 7 to 15 days for samples, 20 to 35 days for a first order, and 15 to 20 days for repeats. Standard full containers can ship in as little as 12 days. A real plan adds the shipping leg to your port, the handover date for each opening, and a phased switch that keeps at least one working bay alive.<\/p>\n<h2 id=\"which-failure-modes-does-the-warranty-name\">Which Failure Modes Does the Warranty Name<\/h2>\n<p>The warranty length is the least informative number in the whole quote, and that is a view we hold firmly. Two years tells you nothing about whether a snapped lifting cable or a voltage-killed control board is covered. Trade discussion threads repeat one complaint in a hundred accents: labour warranty and parts warranty point in opposite directions, and the buyer stands in the middle.<\/p>\n<figure><img decoding=\"async\" src=\"https:\/\/www.raxdoors.com\/wp-content\/uploads\/2026\/08\/loading-dock-door-category.jpg\" alt=\"Loading dock door hardware listed in a supplier quote scope\" width=\"1120\" height=\"680\" class=\"wp-image-1459\" loading=\"lazy\"><figcaption>Name the parts, not just the years<\/figcaption><\/figure>\n<h3>Why Warranty Years Mislead<\/h3>\n<p>Suppliers like round numbers because round numbers end the conversation. Naming exclusions invites questions, so the datasheet says &#8220;2-year warranty&#8221; and the exclusions live nowhere you will find them at claim time.<\/p>\n<h3>What a Usable Warranty Names<\/h3>\n<p>A usable warranty is a list, not a length. Ours names its parts: two years on the door body, three years on operators and motors, five on servo motors. Ask every bidder the same three things. Which failure modes are excluded, which components count as wear items, and who pays freight on a claim part.<\/p>\n<h2 id=\"who-stocks-spares-and-answers-the-phone\">Who Stocks Spares and Answers the Phone<\/h2>\n<p>Doors fail at the worst hour of the quarter, and the quote never mentions that day. A dock standing open at a frozen-food site costs more per hour than most spare parts cost outright. Response time is therefore a purchasing parameter, not a service afterthought. Ask what happens in the first week after a failure, in writing.<\/p>\n<h3>Why Spare Parts Get Promised Vaguely<\/h3>\n<p>&#8220;Full parts support&#8221; is free to promise because it carries no number. The costly version, a named dispatch time and drawings you can archive, takes infrastructure. Suppliers without that infrastructure sell the same words anyway.<\/p>\n<h3>What a Service Answer Puts in Writing<\/h3>\n<p>Make the supplier commit to three artifacts: a spares kit for your exact door, a dispatch commitment for warranty parts, and documentation ownership. We hold customer CAD files for five years under NDA, and warranty parts ship by DHL or FedEx within 5 to 7 days. A supplier who matches that closes the service chain. The broader door-performance logic behind it is covered in our guide to <a href=\"https:\/\/www.raxdoors.com\/blog\/choosing-high-performance-door\/\">choosing a high performance door<\/a>.<\/p>\n<h2 id=\"turn-the-five-questions-into-award-criteria\">Turn the Five Questions into Award Criteria<\/h2>\n<p>Questions asked once, verbally, evaporate by evaluation day. Each of the five should become a scored line in your comparison sheet: traffic assumptions stated, scope itemised, delivery leg committed, failure modes listed, spare-parts response quantified. Price then competes inside a defined scope instead of against it. That discipline is the whole craft behind the right questions when specifying an industrial door.<\/p>\n<p>Back at the meeting table, the three quotes now answer one brief. Two never priced installation, and one excludes the failure you fear most. That is not a procurement failure; that is the set of questions when specifying an industrial door doing its job. The cheapest comparable bid is finally visible.<\/p>\n<h2 id=\"frequently-asked-questions\">Frequently Asked Questions<\/h2>\n<div class=\"faq-card\">\n<h3>What should I ask an industrial door supplier before ordering?<\/h3>\n<p>Ask five things: peak traffic at the opening, whether the quote covers installation and acceptance, the delivery plan, excluded warranty failure modes, and the spare-parts dispatch commitment.<\/p>\n<\/div>\n<div class=\"faq-card\">\n<h3>What is the difference between supply-only and turnkey quotes?<\/h3>\n<p>Supply-only ends at the shipping port or factory gate, with your contractor handling installation. Turnkey includes fitting and commissioning. Both are legitimate, but a comparison is only fair when every bidder prices the same scope.<\/p>\n<\/div>\n<div class=\"faq-card\">\n<h3>How many cycles per day should an industrial door handle?<\/h3>\n<p>It depends on the hardware class. Count real peak-hour movements first, then match springs, motor duty grade, and speed band to that count. Light-use doors suit tens of cycles daily; high-traffic openings need components rated for tens of thousands.<\/p>\n<\/div>\n<div class=\"faq-card\">\n<h3>What documents should come with an industrial door delivery?<\/h3>\n<p>Expect factory inspection records, installation manuals with CAD drawings and wiring diagrams, packing lists with batch numbers, and conformity documents such as a CE declaration under EN 13241. Request the list before ordering, not at unloading.<\/p>\n<\/div>\n<div class=\"faq-card\">\n<h3>How fast should spare parts for industrial doors arrive?<\/h3>\n<p>Ask for a written dispatch time. Our warranty parts ship by DHL or FedEx within 5 to 7 days, plus local transit.
