Fire Rated Industrial Steel Door — RAX Door Technology

01 · Overview

Fire Protection for Industrial Facilities

Fire rated industrial steel doors are engineered to maintain fire compartmentalization in industrial facilities. Unlike standard industrial doors, fire rated doors use mineral wool cores and intumescent seals that expand during fire to block smoke and flame propagation. Fire resistance ratings from EI30 to EI120 (30–120 minutes) protect personnel and property during fire emergencies.

RAX manufactures fire rated industrial steel doors with mineral wool cores, intumescent seals, and heavy-duty steel construction. Opening speeds up to 1 m/s minimize exposure time during each opening cycle. Fire rated doors are certified per EN 16034 and tested per EN 1634-1.

These doors are essential for industrial facilities with fire compartment requirements, warehouses with fire load, manufacturing plants with fire risks, and any environment where fire protection is critical.

02 · Key Features

Engineered for Fire Protection

Mineral Wool Core

Non-combustible mineral wool core (density 145–180 kg/m³) provides fire insulation. Unlike PU foam cores that burn, mineral wool maintains structural integrity during fire. Core density critical for fire rating performance.

Intumescent Seals

Graphite-based intumescent seals expand 25× at 150°C to block smoke and flame propagation. Perimeter seals on all four sides prevent fire spread through gaps. Critical for maintaining fire compartmentalization.

Heavy-Duty Steel Construction

0.7–0.9 mm galvanized steel skins (thicker than standard 0.3–0.6 mm). Reinforced construction withstands fire exposure. Steel maintains structural integrity at high temperatures.

Fire Rating Certification

EI30/EI60/EI90/EI120 ratings (30–120 minutes). Certified per EN 16034 and tested per EN 1634-1. Complete documentation package for building code compliance.

High-Speed Operation

Opening speeds up to 1 m/s with servo motor drive. Frequency converter for smooth acceleration/deceleration. Minimizes exposure time during each opening cycle.

Safety Systems

Photocells detect objects in door path. Pressure-sensitive bottom edge stops door on contact. Emergency stop buttons on both sides. Compliant with EN 12453.

Where Fire Rated Doors Excel

Industrial Facilities with Fire Compartments

Manufacturing plants with fire compartment requirements. Fire rated doors maintain compartmentalization during fire. Protects personnel and property. Required by building codes for large facilities.

Warehouses with Fire Load

Storage facilities with flammable materials. Fire rated doors prevent fire spread between zones. Intumescent seals block smoke propagation. Critical for life safety.

Chemical Plants

Chemical processing and storage facilities with high fire risk. Fire rated doors contain fire within compartments. Mineral wool cores resist chemical exposure.

Power Generation Facilities

Power plants and electrical substations with fire risks. Fire rated doors protect critical infrastructure. Fast operation supports emergency access.

Automotive Manufacturing

Vehicle assembly plants with paint shops and welding areas. Fire rated doors separate high-risk zones. Fast operation supports production line speed.

Food & Beverage Production

Production facilities with ovens and heating equipment. Fire rated doors contain fire risks. Hygienic mineral wool cores easy to clean.

06 · 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

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

CE Marking

Mandatory for fire doors exported to EU/UK markets. 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/hot gas), I = Insulation (prevents heat transfer). EI30 = 30 min, EI60 = 60 min, EI90 = 90 min, EI120 = 120 min.

What is the difference between fire rated and standard industrial doors?

Fire rated doors use mineral wool cores (145–180 kg/m³) with thicker steel skins (0.7–0.9 mm). Intumescent seals expand at 150°C to block smoke. Standard doors use PU foam cores. Fire doors are certified assemblies — component substitution voids certification.

What certifications are required for fire doors?

EU/UK markets require EN 16034 + EN 1634-1 + CE marking. Fire doors must have Declaration of Performance under CPR 305/2011. RAX provides complete certification package.

Can components be substituted on fire doors?

No. Fire doors are certified as complete assemblies. Any component substitution may void certification. Technical drawings must list exact components used in testing.

Do you provide installation?

No — RAX is a pure manufacturer. Doors ship with English installation manuals, wiring diagrams, and remote support.

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, motor and control 5 years.
