30" x 54" Aluminum Ship Stair Access Roof Hatch - Bilco

When it comes to installations that require frequent access, our Type NB Ship Stair Access Roof Hatches will be ideal for use. These doors permit more effortless movement of personnel, maintenance, tools, and equipment. 

The Type NB features a cover with break formed, a hollow-metal design with 25mm concealed fiberglass insulation, 76mm beaded, overlapping flange, fully welded corners, internally reinforced for 195 kg/m2 live load. Its curb is 305 mm in height with integral cap flashing, fully-welded at corners, and with 25mm fiberboard insulation. To ensure that the cover opens with ease, this door model also comes with compression spring operators. The overlapping cover design, full welded corners on cover and curb, EPDM rubber gasket, and fully insulated cover and curb ensure weather tightness and energy efficiency.

The material is corrosion-resistant, ensuring that all harsh weather elements won’t damage it and won’t give you trouble for a long time. You can get it at BestRoofHatches in galvanized steel, aluminum, or stainless steel construction, in different available and special sizes depending on what specifications you need.
