48" x 48" Equipment Access Roof Hatch - Stainless Steel - Bilco

F-90 – 48" x 48" Equipment Access Roof Hatch – Stainless Steel  - Bilco 

F-90 Equipment Access Roof Hatch – Stainless Steel is a single cover access door that allows service personnel to bring and install equipment not larger than 48" x 48"(1220mm x 1220mm). It has several features that most building needs. These features include corrosion-resistant, durability, and longevity, making it an ideal equipment access roof hatch for most structures, especially in places that frequently experience harsh weather or are in marine settings.  

Why Install F-90?  

Durability: Bilco equips the F-90 equipment access roof hatch's cover and frame with 14 gauge (2 mm) Type 304 Stainless Steel thick to ensure its structural design to hold equipment, materials, or live load of 40 psf (195 kg/m2) 

Hygienic: Mold formation is a health hazard that every building owner must regularly consider, as it can severely impact the occupants' physical and can trigger allergies and respiratory illnesses. Reduce the risk by using F-90. Stainless steels are non-porous, preventing or reducing the building's bacterial growth.  

Low Maintenance: The F-90 appearance and structural integrity are easy to maintain. Its primary material, stainless Steel,  which is highly resistant to corrosion, only needs occasional maintenance. Additionally, it only needs water and stainless-steel-friendly cleaning products to clean it.
