Fire Rated Steel Door Prepared for Your Project Specification

When comparing fire rated steel door suppliers, focus on required fire rating, local code, certification scope, opening size, wall construction, handing, hardware set, closer, seals, and installation responsibility. These decisions affect fit, reliability, installation, and the total value of the final door.

YUOU develops the proposal around your project information. We can coordinate the rated leaf and frame, approved hardware, glazing where permitted, closer, seals, lockset, and wall fixing details within the available certification scope so you can compare a defined configuration instead of only a headline price.

YUOU fire rated steel doors can be customized for project dimensions and architectural finishes while coordinating the door leaf, frame, seals, and fire-rated hardware as a complete system. Fire rating and certification documents should be matched to the local code and approval requirements of each project before production.

Product Details

Use the following product details to compare suppliers against the same project requirements. YUOU can review these items with your drawings before the final configuration and quotation are confirmed.

Structure Diagram

The structure diagram shows the reinforced steel door leaf, internal fire-resistant core, frame, hinges, intumescent sealing positions, and hardware arrangement. It helps buyers, contractors, and approval teams review how the complete fire door assembly supports compartmentation and emergency operation before drawings are confirmed.

Door Panel

The double-layer door leaf uses high-quality 1.0mm galvanized steel plates reinforced by internal U-shaped steel channels. This structure helps the fire rated steel door resist bending and deformation under thermal stress, maintain alignment, and remain operable during emergency evacuation.

The inner cavity is densely filled with high-density rock wool board to reduce radiant heat transfer. An industrial anti-corrosion powder-coated finish improves durability and weather resistance for demanding commercial and industrial environments.

Window

An optional fire-rated vision panel provides visibility through the door while maintaining the specified fire-resistance duration, starting from 90 minutes. Depending on project requirements, the glazing can use wire glass or transparent ceramic fire-rated glass designed to withstand high temperature and thermal shock.

Heavy-duty cold-rolled steel glazing beads and continuous high-temperature intumescent seals secure the glass perimeter. During a fire, the sealing system expands to restrict flame and smoke passage around the opening and support the integrity of the evacuation route.

Lock

The fire rated steel door can be configured with heavy-duty fire-certified locks and handles that support emergency egress while maintaining controlled access from the secure side. The existing hardware specification uses 304 stainless steel for resistance to high-frequency use and demanding commercial environments.

Lockset, handle, panic hardware, and access-control preparation should be selected together with the required fire rating, opening direction, and local egress rules so the final door assembly performs correctly in both daily use and emergencies.

Door Closer

The door closer automatically returns the fire rated steel door to the closed position, helping restore the fire compartment after passage. The closer uses a die-cast aluminum body and precision hydraulic mechanism, with adjustable closing and latching speeds for different door sizes and weights.

Correct closer selection and adjustment support smooth daily operation, reliable latching, and long-term fire-safety performance. The closer should be coordinated with the door weight, hinges, lockset, seals, and any access-control hardware.

Advantages

Choose YUOU when you need the fire rated steel door to be coordinated with the opening, operating process, installation conditions, and purchasing requirements rather than supplied as a generic standard configuration.

90-120 Minute Fire-Resistance Options

Available fire-resistance durations of 90 to 120 minutes support different compartmentation requirements. The required rating, test standard, and certification documents should be confirmed against the project specification and local approval rules.

Reinforced Steel Structure Under Heat

Door leaves use 1.0-1.5mm galvanized steel with internal U-shaped reinforcement and high-density rock wool or perlite infill. This construction helps limit warping, maintain alignment, and protect emergency operation under thermal stress.

Coordinated Egress and Security Hardware

Panic bars, fire-rated closers, locks, handles, and electronic access-control preparation can be coordinated as a system. This supports immediate exit from the egress side while maintaining controlled access and everyday building security.

Project-Specific Sizes and Finishes

Single or double doors, oversized industrial openings, RAL powder-coated finishes, fire-rated vision panels, and hardware configurations can be customized while keeping the required fire rating and architectural appearance aligned.
