Essential Guide to Access Hatches & Trap Doors for Industrial and Roof Applications

15 Jul, 2025

In industrial and commercial buildings, providing safe and discreet access to roof areas, utility shafts, mezzanines, or concealed service zones is not just a convenience—it’s a necessity. Access hatches and trap doors from Geometric Steels offer smart, secure, and thermally insulated solutions for such requirements.

Whether installed on metal roofs, RCC slabs, or factory floors, our hatches are built for performance, durability, and safety.


What Are Access Hatches & Trap Doors?

Access hatches are specialized openings in roofs or floors that allow safe entry to areas above or below a structure. Commonly used by maintenance teams or facility operators, they are engineered to be weatherproof, secure, and load-bearing.

Trap doors, typically floor-mounted, serve a similar function but are often flush with the floor and designed to blend in seamlessly while offering quick access to equipment, cables, or service paths.

Types of Access Hatches Offered by Geometric Steels

We manufacture a range of custom-engineered hatch systems to suit varied structural conditions and usage patterns:

Metal Surface-Mounted Roof Hatch

 Installed over metal sheeted roofs, especially in pre-engineered buildings (PEBs) and large industrial sheds. These are factory-built, weather-sealed hatches with thermal insulation and anti-corrosive finishes.

Slab-Mounted Roof Hatch

 Designed for RCC roof slabs and concrete structures, these hatches provide secure access while blending with masonry surfaces.

Drainable Floor Hatch

 Ideal for utility areas or outdoor zones. These come with slope-edge designs and built-in drain holes to prevent water accumulation.

Non- Drainable Floor Hatch

Useful for indoor floor access, these are made for easy and secure access to your underground indoor facilities, without extra construction cost to build doorway.

Built for Safety, Performance & Longevity

Geometric Steels access hatches are designed with long-term performance and user safety at their core. Here's what makes them stand out:

Weather-Resistant Sealing & Drainage

Built-in slope-edge frames, water-tight sealing gaskets, and drainage channels ensure that water never enters the building—even during heavy rain.

Thermal Insulation Layer

A high-performance thermal break system helps regulate indoor temperature by preventing heat ingress through the hatch, especially important in temperature-controlled environments.

Smooth & Safe Operation

Gas-spring struts provide effortless opening and hold functionality, eliminating the risk of injury during operation. Some models also come with anti-slip surfaces for added safety.

Rugged Build & Load Capacity

Made from mild steel (MS), galvanized steel, or stainless steel, our hatches meet industrial load-bearing requirements and are available in customizable thicknesses and profiles.

Installation & Maintenance Best Practices

Choose the right hatch type based on roofing surface (metal sheet or RCC) and access needs.


For metal roof installations, prefer factory-built surface-mounted hatches with pre-engineered sealing.


Ensure periodic inspection of hinges, struts, seals, and drainage paths to retain long-term usability.


Always consider thermal insulation for hatches exposed to direct sunlight.
