Galvanized Steel Fire Escape Staircase - Perforated Staircase

We supply galvanized steel staircases for factories, plants, fire escapes. Fire escape stairs can also be supplied in aluminum or stainless steel perforated sheet for higher budget projects.

Our architectural metal works are used both for construction of new fire escape staircases or installation of new fire escape stairs in replacement of the old stairs.

Fire escape stairs are emergency exits mounted mostly to outside of the buildings, providing a means of flight from fire or other emergency events inside the building.

Fire escape stairs are constructed with three metal structural elements: horizontal platforms, steel walkways / ladders or stairs, hand railings.

Metal steel platform floor and and stair treads are usually made of steel grating panels with anti slippery checkered plates.

In producing and supplying fire espace staircase, we always abide following three major principles:
Safety guaranteed by stable and adequate strength proved by load test or other means;
Safety guaranteed by anti slippery design of exterior stairways: the fire escape shall be made against fire, snow and slipping;
Safety guaranteed by meeting related International Fire Code Testing and Certifications required from different countries for exterior bridges, stairways, fire escapes, balcony railings panels structural adequacy and safety at set period.
