1. Simple introduction
It is widely preferred for roofs and wall cladding. Our company designs these profile sheets
using authentic stainless steel metal, which has strong tensile strength.also known as the
pre-painted galvanized steel coil, color steel coil etc, typically with a hot dip zinc coated
steel substrate. It refers to factory pre-painted zinc coated steel, where the steel is painted
before forming
2. Main usage
It is often used as building materials(ceiling, metal roof tile) machinery parts(electrically
controlled cabinets,road maintain board, etc, It is mainly used in advertising industry,
construction, household appliances industry, electrical industry, furniture industry and
transportation
3. Quality control
Strict procurement process---skillful technical workers---final products inspection(resistance
to corrosion, salt spray test, exposure test, machinability, thermal resistance)---standard packing
