Hollow Metal Door Data Sheet | Technical Specification & Performance Guide

Introduction

A Hollow Metal Door is one of the most widely used door systems in commercial, industrial, and institutional buildings across North America, the Middle East, and global construction markets. Known for its durability, fire resistance, and security performance, hollow metal doors are a standard solution for hospitals, schools, hotels, warehouses, and high-rise buildings.

This page provides a complete Hollow Metal Door Data Sheet, including material specifications, thickness options, fire ratings, frame details, and hardware compatibility-helping architects, contractors, and procurement teams make informed decisions.

1. Hollow Metal Door Construction

Hollow metal doors are typically manufactured using cold-rolled or galvanized steel sheets, reinforced internally with honeycomb, polyurethane, or mineral core materials.

Standard Structure:

Face sheet: 20GA / 18GA  (1.0mm /1.2mm )

Core material: Honeycomb(Hollow core ) / Mineral Core(insulated core)

Internal reinforcement: Steel stiffeners at lock & hinge locations

Adhesive: High-strength industrial bonding system
