A layer of polyurethane foam bolsters noise suppression and delivers insulation up to four times better than typical wood doors. It also serves as a unifying agent, anchoring all interior components securely for added resilience.
A specialized hinge plate is embedded in the door slab, allowing convenient adjustments in any direction without taking the door off the frame. A simple screwdriver is all that’s needed for quick modifications at any point.
Incorporating a composite lock block helps ensure secure hardware installation and strengthens the door’s overall structure. Compared to wood, the reinforced block delivers superior screw‑holding capacity.
With a steel-edge design, these doors surpass the toughest forced-entry benchmarks in the industry. To achieve a Grade 40 certification, a door must endure over seven blows from a 100‑pound test weight.
Constructed from 22- or 24-gauge hot-dip galvanized steel, this premium fire door resists cracking, splitting, warping, twisting, rotting, and corrosion. Its full steel-edge perimeter achieves a Grade 40 Security Rating, while 20-gauge hinge reinforcements and a polyurethane foam core provide excellent durability and insulation. Certified for 90-minute fire protection, it also features a baked-on polyester primer that accepts exterior-grade latex paint.
