Garage Door — RAX Door Technology
01 · Overview

Versatile, Insulated, and Built to Last

The sectional garage door is the most versatile garage door type — panels slide vertically on tracks, requiring no swing-out clearance, providing full drive-through width, and offering superior insulation compared to single-panel doors. Sectional doors are the standard choice for modern residential garages, commercial buildings, and industrial facilities worldwide.

RAX manufactures sectional garage doors with 40–50 mm PU foam insulated panels (galvanized steel skins 0.4–1.5 mm), achieving U-values as low as 0.5 W/(m²·K). Torsion spring counterbalance system with cable break and spring break safety devices. Full RAL color matching and Decograin wood-grain finishes available. Electric automation with soft-start/soft-stop, remote control, and emergency release. Wind resistance rated to Class 3 (700 N/m²) per EN 12424.

Sectional garage doors are suitable for residential detached garages, underground parking, commercial buildings, light industrial workshops, and any application where insulation, security, and space efficiency are priorities. They outperform up-and-over doors in insulation, sealing, and space utilization, and outperform roll-up doors in thermal performance and cycle life.

02 · Key Features

Why Sectional Doors Are the Standard Choice

Zero Front Clearance

Panels slide vertically on tracks — no swing-out clearance required. Door opens directly onto driveways, walkways, or narrow passages. Full drive-through width preserved (unlike up-and-over doors that reduce width).

Superior Insulation

40–50 mm PU foam core with U-value as low as 0.5 W/(m²·K). Inter-panel seals reduce air infiltration. EPDM perimeter seals top, bottom, and sides. Ideal for climate-controlled garages and attached garages.

Torsion Spring System

Shot-peened torsion springs rated for 25,000+ cycles with dual anti-fall protection (cable break + spring break devices). Spring tension calibrated to door weight for smooth manual or electric operation.

Multi-Point Locking

Standard multi-point locking system. Electric versions include triple-pin securing and 128-bit encrypted remote control. Anti-lift brackets prevent forced entry. Optional SBD certification for enhanced security.

Full Customization

Custom width × height to any opening. Full RAL color matching. Decograin wood-grain finishes. Window inserts available. Panel textures: smooth, stucco, woodgrain, ribbed. Custom track configurations (standard, high lift, vertical lift, low headroom).

Electric Automation

Soft-start/soft-stop motor with wireless remote control (128-bit encryption), force limiter, photocells, and auto-reversing. Emergency release for manual operation during power failure. Optional smart home integration.

04 · Applications

Versatile for Every Building Type

Residential Detached Garages

The standard choice for modern homes. Zero front clearance suits driveways and tight spaces. Superior insulation protects attached living spaces from temperature transfer. Full RAL and Decograin finishes match any home aesthetic.

Underground & Basement Parking

Vertical sliding design requires no swing-out space — ideal for underground garages with restricted headroom. Low headroom track configurations available. Security features protect vehicles and property.

Commercial Buildings

Loading bays, service entrances, and commercial garages. Larger sizes available (up to 8 m wide). Electric automation for high-frequency use. Insulation maintains interior climate control.

Workshops & Light Industrial

Workshops requiring insulated, secure access. Full drive-through width accommodates equipment and vehicles. Multi-point locking secures valuable tools and materials. Optional wicket door for pedestrian access.

Attached Garages

Sectional doors provide the best thermal barrier between attached garage and living space. U-value 0.5 W/(m²·K) reduces heating/cooling loss. EPDM seals prevent drafts and moisture ingress.

Retrofit & Replacement

Replace old up-and-over or roll-up doors with modern sectional doors. Available in standard sizes for common openings. Low headroom configurations fit spaces originally designed for older door types.

05 · Customization

OEM / ODM & Customization

RAX supports full private-label production of the Garage Door: custom panel thickness (40/50 mm), RAL color matching, Decograin wood-grain finishes, operator matching, track configuration, packaging printing and installation-manual translation (EN/ES/FR/AR/RU). Start with an OEM sample and scale to container-load branded production. Custom molds and tooling records are archived for up to 5 years — no extra tooling fee on repeat orders, all under strict NDA.

06 · Compliance

Applicable Standards

EN 13241:2003+A2:2016

Core CE product standard for industrial, commercial, and garage doors. Covers both manual and powered doors. Requires Declaration of Performance (DoP) under CPR 305/2011.

EN 12424:2000

Wind load resistance classification. Defines Classes 0–5 (300 N/m² to >1,100 N/m²). Sectional garage doors typically achieve Class 2–3 for residential; higher classes available for exposed sites.

EN 12453:2001

Safety requirements for powered doors. Specifies force limiting, safety devices, and control system requirements. Electric garage doors must comply with the Machinery Directive.

CE Marking

Mandatory for export to EU/UK markets. Indicates compliance with EN 13241 and CPR 305/2011. RAX provides CE technical file and Declaration of Performance with every shipment.

Why choose a sectional garage door over other types?

Sectional doors offer: zero front clearance (unlike up-and-over), superior insulation (U-value 0.5 W/m²K vs. R-6 to R-10 for roll-up), full drive-through width, higher cycle life (25,000+ vs. 10,000–20,000 for roll-up), and better sealing against weather. They are the most versatile garage door type for residential and commercial applications.

What insulation performance do sectional doors provide?

RAX sectional doors achieve U-value as low as 0.5 W/(m²·K) with 40–50 mm PU foam core. Inter-panel EPDM seals reduce air infiltration. Full perimeter sealing (top, bottom, sides) prevents drafts. This makes them suitable for attached garages and climate-controlled spaces.

What track configurations are available?

Standard lift (300–500 mm headroom), high lift (for vertical space above opening), vertical lift (for maximum ceiling clearance), and low headroom (100–175 mm for tight spaces). Track selection depends on your ceiling height and overhead obstacles.

Are sectional garage doors secure?

Yes. Standard multi-point locking. Electric versions include triple-pin securing system and 128-bit encrypted remote control. Anti-lift brackets prevent forced entry. Optional Secured by Design (SBD) certification for enhanced residential security. For high-security applications, specify SBD + reinforced locking.

Can sectional doors be automated?

Yes. Electric operators with soft-start/soft-stop, wireless remote control (128-bit encryption), force limiter, photocells, auto-reversing, and emergency release. Optional smart home integration and ventilation mode (door lifts 10 cm, auto-closes after 60 minutes).

Do you provide installation?

No — RAX is a pure manufacturer. Doors ship with English installation manuals, wiring diagrams, and remote support. We recommend using a qualified local installer who can verify structural capacity and proper track alignment.

What is the lead time and warranty?

Standard configurations: 12–20 days. Custom first order: 20–35 days. Repeat orders: 15–20 days. Warranty: panels 10 years, automation components 5 years. Warranty replacement parts shipped via DHL/FedEx in 5–7 days.
