A36 SS400 Standard Steel Strut Channel Galvanized Coated Q235 JIS ASTM Steel profile

Products :

Galvanized C - shaped steel has uniform zinc layer , smooth surface , strong adhesion and high dimensional accuracy . All surfaces are wrapped by zinc layer . The zinc content on the surface is usually 120 - 275g / ㎡. It has long service life , corrosion resistance and durability . It is a kind of galvanized C - shaped steel with the strongest protection . It is of high quality. Galvanized steel is among the most popular steel types because of its extended durability, having the strength and formability of steel plus the corrosion protection of the zinc-iron coating.

Introduction to C-section steel :

C - section steel can be used not only as standard reinforcement and wall beam in steel structure buildings , but also as standard reinforcement in buildings . It can also be combined into light roof trusses , supports and other building components . This necessarily involves cutting steel . Because different cutting methods have different cutting effects , it is necessary to make appropriate choices according to customer requirements.
If C - section steel is used in steel structure , it shall be cut on shear machine or sawing machine as far as possible , which is applicable to thin-walled steel roof truss . Due to the high cutting accuracy , the electric saw method is more suitable . It not only has high working efficiency , but also has smooth and flat section , good quality and small cutting error .
Gas cutting can also be used , but in order to improve the quality of gas cutting , please try to use a small-diameter nozzle and tap it gently with a hammer after cutting to make the cutting smooth and meet the requirements of various purposes . Like other cold-formed sections , the problem faced in production is internal stress . Due to the large internal stress of the material , it may deform after use , thus affecting its use effect .
The main reason for the inevitable stress is that certain stress will be produced through forced mechanical deformation . In addition , the primer is not sprayed , so the rust removal and passivation process will release its internal stress , which will lead to bending and distortion .
If it is unavoidable , only reasonable operation can be used to reduce the pressure . As manufacturers and users , we must also pay attention to this problem to ensure that C - section steel can be widely used .
