Here's a breakdown of what goes into our industrial fire rated doors and fireproof internal doors to ensure they deliver uncompromising protection.
1. High-Gauge Steel: The Backbone of Fireproof Security Doors
Every fireproof security door starts with heavy-duty steel. We use 14- to 16-gauge cold-rolled steel for the outer shells because it resists warping under heat and physical attacks. Unlike thinner metals, our industrial fire rated doors maintain structural integrity even when exposed to prolonged fire conditions. For fireproof internal doors, we often reinforce the steel core with additional layering to prevent heat transfer.
2. Mineral Wool & Ceramic Insulation: The Fire Barrier
Raw steel alone isn't enough—what's inside matters just as much. Our fireproof security doors are packed with mineral wool, a non-combustible insulation that slows heat transfer. For higher fire ratings (up to 120 minutes), we incorporate ceramic fiber panels, which can withstand temperatures exceeding 1,800°F. These materials are key in both industrial fire rated doors for factories and fireproof internal doors for office partitions.
3. Intumescent Seals: Expanding Under Fire
A door is only as strong as its seals. Our fireproof security doors feature intumescent strips around the edges. When exposed to heat, these seals expand up to 10 times their size, sealing gaps to block smoke and flames. This tech is standard in our industrial fire rated doors, ensuring compliance with strict safety codes. Even our fireproof internal doors include narrower intumescent seals for compartmentalization in buildings.
4. Reinforced Frames & Multi-Point Locking
A weak frame ruins even door. Our fireproof security doors come with steel or reinforced aluminum frames, welded for extra rigidity. For industrial fire rated doors, we integrate multi-point locking systems—usually 3 to 5 bolts—that distribute force evenly. This prevents intruders from prying them open, making them as secure as they are fire-resistant.
5. Fire-Rated Glass (When Visibility Is Needed)
Not all fireproof internal doors need to be solid metal. For offices or corridors requiring visibility, we install fire-rated ceramic glass. Unlike regular glass, it stays intact under high heat, maintaining a barrier while allowing light and visibility. In industrial fire rated doors, we often pair this with wire mesh for added security.
6. Powder-Coated Finishes for Longevity
Even tough fireproof security door can rust if poorly finished. We apply electrostatic powder coatings that bond chemically to the steel, creating a scratch- and corrosion-resistant layer. This is crucial for industrial fire rated doors in harsh environments, from chemical plants to coastal buildings.
7. Testing & Certification: How We Guarantee Performance
Before any fireproof security door leaves our factory, it undergoes brutal testing:
- Furnace Exposure – Can it withstand 2+ hours of direct flames?
- Hose Stream Test – Does it stay intact when hit with high-pressure water immediately after fire exposure?
- Forced Entry Simulation – Can it resist drilling, prying, and kicking?
Our industrial fire rated doors meet UL, NFPA, and local fire codes, while our fireproof internal doors are tested for compartmentalization in multi-story buildings.
Why These Materials Matter for Buyers
Whether you need fireproof security doors for a data center, industrial fire rated doors for a warehouse, or fireproof internal doors for a hotel, the materials dictate performance. Cheap alternatives might save money upfront but fail when it counts.
At our factory, we don't cut corners—because when fire strikes, there's no room for error. Every layer in our doors serves a purpose: stopping flames, resisting attacks, and lasting decades. That's not just manufacturing—it's peace of mind, built to order.
