HMPS Doors Explained: Why Hollow Metal Pressed Steel is India's Industrial Door Standard

HMPS (Hollow Metal Pressed Steel) doors are the go-to solution for factories, hospitals, commercial complexes, and government facilities across India. Engineered for durability, security, and fire safety, they set the benchmark for industrial door performance.

What are HMPS Doors?

HMPS stands for Hollow Metal Pressed Steel. These are doors fabricated by cold-pressing steel sheets into profiled door skins, then assembling them around a structural steel framework and filling with an insulating core. The result is a strong, consistent, and fire-resistive door assembly.

Unlike traditional welded steel doors, HMPS doors are pressed to precise tolerances, resulting in a flatter, more uniform surface that looks better and performs better in fire tests.

How HMPS Doors are Made at Acodor

1. Steel coil pressing: CR (Cold Rolled) steel sheets are pressed using hydraulic presses into the door skin profile
2. Frame welding: Internal steel frame is MIG welded for structural integrity
3. Core filling: Ceramic wool or rock wool is packed for fire insulation; honeycomb for acoustic variants
4. Assembly and bonding: Door skins are bonded and mechanically fastened to the frame
5. Surface treatment: Shot blasting, zinc phosphating, and epoxy powder coat finish
6. Hardware fitting: Certified hinges, locks, closers, and intumescent seals are fitted

Why HMPS is Preferred Over Conventional Steel Doors
