A hatch is installed on a roof, usually a flat roof. Roof hatches are normally, pre-assembled units that are purchased from companies that specialize in making roof hatches. The hatch is normally installed on the roof prior to the roofing installation, or a curb is set on the roof prior to the installation of the roof membrane.
This sequencing allows the roofer to either flash against the actual roof hatch itself, or the installed curb. Roof hatches normally open from the inside and has a ladder that rises up within the hatch from the last floor of the structure. Commercial roof hatches are used for servicing mechanical units located on the roof and for normal maintenance requirements.

Roof hatches can be equipped with smoke detectors and or fire detectors to allow the roof hatch to open upon smoke or fire. The opening of the roof hatch will allow venting to occur and clearing of the structure of smoke.
There are several types of roof hatches, that depending on the needs of the structure, can offer totally maintenance-ready access to the roof, or a more mellow approach for access to a roof garden or patio. Modern roof hatches are equipped with springs or hydraulic pistons to aid in opening and closing as well as waterproof gaskets to ensure that the roof hatch does not leak.
Protect your commercial HVAC systems from roof leaks and damage with heavy-duty roof support frames. Rooftop HVAC duct supports are not intrusive and can withstand high winds, snow loads, and other environmental hazards.
HVAC support frames are available in hot-dipped galvanized or pre-galvanized finishes. They can bear up to 400 pounds. 120 mph winds. Rooftop support frames allow for adjustable elevation and flexibility in application to suit your specific project needs. Professional framers can help you design and engineer your project.
Steel framing is usually constructed in a rectangular grid. This grid supports the floor, roof, and walls attached to it. This is how skyscrapers were built. Steel frames are also used to frame warehouses and industrial buildings. Although steel-framed structures are more expensive than wooden frames, they offer many benefits.
Steel is strong and durable, which makes it a great choice for any structure. Steel is also durable, waterproof, and resistant to fire. Steel will bend to its own shape and not crack like glass. Although this is not always true for all the materials attached to it; a steel skeleton structure will be strong. Steel is lighter than wood and takes less time to build.
Framers are professionals who build and repair wooden structures. Although they may be working on the actual frame of a building, they are also able to build other wooden parts during construction.
