Fire Resistant Sectional Door — RAX Door Technology
01 · Overview

Fire Compartmentalization for Industrial Facilities

Fire resistant sectional doors are engineered to maintain fire compartmentalization in industrial and commercial buildings. Unlike standard sectional doors that use PU foam cores, fire resistant doors use mineral wool/rock wool cores (density 145–180 kg/m³) with thicker galvanized steel skins (0.7–0.9 mm vs. 0.3–0.6 mm standard) to withstand extreme temperatures. Fire resistance ratings range from EI30 (30 minutes) to EI120 (120 minutes), where E = Integrity (prevents flame and hot gas penetration) and I = Insulation (prevents heat transmission).

RAX manufactures fire resistant sectional doors with 53 mm thick panels containing rock wool cores, galvanized steel reinforcement ribs, and graphite intumescent seals that expand 25× at 150°C to block smoke propagation. Low thermal conductivity steel frames (1.5 mm thickness) reduce heat transfer. Doors are certified per EN 16034 (fire and smoke door product standard) and tested per EN 1634-1 (fire resistance test method). CE marking mandatory for EU/UK export.

Fire resistant doors are essential for firewall openings, fire compartment boundaries, escape routes, technical rooms (electrical/mechanical), hospitals, schools, high-rise residential buildings, and industrial facilities requiring fire separation. Note: fire doors are certified as complete assemblies — any component substitution (hardware, seals, glass) may void certification.

02 · Key Features

Engineered for Fire Safety and Compliance

Fire Resistance Ratings

EI30 (30 min), EI60 (60 min), EI90 (90 min), EI120 (120 min). E = Integrity (blocks flame/hot gas), I = Insulation (blocks heat transfer). Rating selection depends on building code and firewall rating requirements.

Rock Wool Core

Mineral wool/rock wool core density 145–180 kg/m³ (vs. PU foam ~42–48 kg/m³ in standard doors). Non-combustible, maintains structural integrity at extreme temperatures. Panel thickness 53 mm.

Intumescent Seals

Graphite intumescent gaskets (15×2 mm) expand 25× at 150°C to seal gaps and prevent smoke propagation. Smoke seal (Sa designation) critical for escape routes and occupied spaces.

Thick Steel Skins

0.7–0.9 mm galvanized steel skins (vs. 0.3–0.6 mm standard). Thicker steel withstands extreme heat without deformation. Galvanized coating prevents corrosion in humid environments.

Certified Assembly

Doors certified as complete assemblies per EN 16034 + EN 1634-1. All components (hardware, seals, glass, dimensions) must match tested configuration. Component substitution voids certification.

Size Range

Width 1,000–8,000 mm, height 1,500–10,000 mm. Track thickness 2 mm. Operating speed 10–15 m/min. Motor power 0.75–1.5 kW. Lift configurations: standard, high lift, vertical lift.

04 · Applications

Where Fire Resistant Doors Are Required

Firewall Openings

Maintain firewall integrity where vehicle/pedestrian access is required. Fire doors must match or exceed the firewall rating (e.g., 2-hour firewall requires EI120 door). Critical for industrial facilities with fire compartment requirements.

Fire Compartment Boundaries

Separate industrial areas and rooms into fire compartments to limit fire spread. Required by building codes for large facilities. Fire doors maintain compartmentalization while allowing necessary access.

Escape Routes

Protect evacuation paths with smoke-sealed fire doors (Sa designation). Intumescent seals expand to block smoke propagation. Critical for life safety in hospitals, schools, and high-rise buildings.

Technical Rooms

Electrical rooms, mechanical rooms, and boiler rooms with elevated fire risk. Fire doors prevent fire from spreading to adjacent occupied spaces. EI60 minimum typically required.

Hospitals & Schools

High-occupancy buildings require strict fire separation. Fire doors protect evacuation routes and limit fire spread. EI60–EI120 ratings typical for healthcare and educational facilities.

Warehouses & Industrial

Storage areas with fire load (flammable materials) require fire compartmentalization. Fire doors separate high-risk zones from general storage. EI30–EI60 typical for warehouse applications.

06 · Customization

OEM / ODM & Customization

RAX supports full private-label production of the Fire Resistant Sectional Door: custom fire rating (EI30–EI120), RAL frame colors, operator matching, 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. Note: fire door certifications are size-specific — custom sizes outside tested range require additional testing.

07 · Compliance

Applicable Standards

EN 16034

EU product standard for fire and smoke doors. Covers fire resistance, smoke control, and durability. Requires Declaration of Performance (DoP) under CPR 305/2011. CE marking mandatory for fire doors in EU/UK markets.

EN 1634-1

Fire resistance test method for doors and shutters. Tests integrity (E) and insulation (I) under standard fire curve. Determines EI rating (30/60/90/120 minutes). Tests conducted by accredited laboratories.

EN 13241:2003+A2:2016

General product standard for industrial, commercial, and garage doors. Fire doors must comply with both EN 16034 (fire-specific) and EN 13241 (general requirements).

EN 14600

Durability certification for fire doors. C5 rating indicates highest durability class for high-frequency use. Required for doors in busy industrial facilities.

EN 13501-2

EU classification standard for fire performance of construction products. Defines EI rating syntax and additional classifications (durability, smoke control).

CE Marking

Mandatory for fire doors exported to EU/UK markets. Indicates compliance with EN 16034 and CPR 305/2011. RAX provides CE technical file, Declaration of Performance, and fire test certificates with every shipment.

What do EI30, EI60, EI90, EI120 mean?

EI ratings indicate fire resistance duration in minutes. E = Integrity (prevents flame and hot gas penetration), I = Insulation (prevents heat transmission). EI30 = 30 minutes, EI60 = 60 minutes, EI90 = 90 minutes, EI120 = 120 minutes. Rating selection depends on building code and firewall rating requirements.

What is the difference between fire resistant and standard sectional doors?

Fire resistant doors use rock wool cores (density 145–180 kg/m³) with thicker steel skins (0.7–0.9 mm vs. 0.3–0.6 mm standard). Intumescent seals expand at 150°C to block smoke. Standard doors use PU foam cores and EPDM seals. Fire doors are certified assemblies — component substitution voids certification.

What certifications are required for fire doors?

EU/UK markets require EN 16034 (fire/smoke door product standard) + EN 1634-1 (fire resistance test) + CE marking. Fire doors must have Declaration of Performance (DoP) under CPR 305/2011. RAX provides complete certification package with every shipment.

Can components be substituted on fire doors?

No. Fire doors are certified as complete assemblies. Any component substitution (hardware, seals, glass, dimensions) may void certification. Technical drawings must list exact components used in testing. Unauthorized changes invalidate the fire rating.

What applications require fire resistant doors?

Firewall openings, fire compartment boundaries, escape routes, technical rooms (electrical/mechanical), hospitals, schools, high-rise residential buildings, and industrial facilities requiring fire separation. Building codes specify where fire doors are mandatory.

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 seal installation.

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.
