FAQ
常见问题
What thickness of medium- and high-density cementitious spray do I need?
It depends on the member size (section factor), the critical temperature and the required fire rating – the fire engineer or the manufacturer's tested data gives a thickness for each member.
Does World Steel supply branded products?
Yes – we supply the brand and listed system your specification or authority requires. This page describes the product type.
