Steel grating is an open-type steel member that is orthogonally combined with bearing bar steel and crossbars at fixed intervals, and is fixed by welding or pressure lock. The crossbars can be twisted square steel or round Steel or flat steel, the materials are divided into carbon steel and stainless steel. It has the advantages of ventilation, light transmission, non-slip, strong bearing capacity, beautiful operation, easy cleaning, and concise equipment. It is widely used in power stations, shipbuilding, chemical engineering and other fields.
Steel Bar Grating Dimension tolerance:
Whether the diagonal tolerance of the steel grating is controlled within the tolerance range of the standard or within the tolerance range of the contract.
Raw materials selection of bearing bar :
Bearing Bar Flat steel is a steel grating that bears the main load in the entire structure, so the quality of bearing bar raw materials has a great effect on the quality of the finished product.
Proofreading of flat steel parallelism:
The steel bar grating flat steel may not be 100% parallel after welding. In addition, the flat steel will be slightly twisted due to hoisting during transportation. If the steel grating is a little twisted, the welding will not be possible, or the welded steel The grid plate is deformed, so proofreading is very important.
Steel Bar Grating Welding:
Welding is a very important part. The quality of welding will directly affect the load-bearing capacity of the steel grating and its life span. If the welding quality is poor, the welding may be started after a few days. Such a steel grating cannot use.
Surface treatment:
Hot-dip galvanizing of steel grating: hot-dip galvanizing is very important to steel grating. Hot-dip galvanizing is not only beautiful, but also its anti-rust ability and anti-corrosion ability. The quality of hot-dip galvanizing is good and it will last naturally. The number is long.
