keel

1:Sophisticated manufacturing equipment, production technology, advanced detection methods of science, the product surface, rolling, high precision, beautiful shape, straight.

2:Using the haih quality continuous hot-dip galvanizing cold-rolled coil for the base material ,material evenly ,moderate hardness , light weight , fireproof, combination convenience , Not subject to seasonal effects, the construction simple and quick, greatly shortening the duration and improve the working efficiency

3:The amount of double-sided galvanized is 120g / m2 . rust corrosion resistance ability, long service life

4:Cross-section structure is reasonable, humane design: Keel, Vice keel and vertical played pitting self-tapping screw designed to effectively prevent sideslip, improve the construction speed, Vice-keel edge of the stiffener designed to enhance the steel keel, anti-subsidence more capable, The level of vertical keel edge design makes perfect fastening, an increase of product application design
