When installing steel grating, there are two common installation methods, one is bolting, and the other is welding. Steel grating is an open steel member that is orthogonally combined with load-bearing flat steel and cross bars according to a certain interval, and is fixed by welding or press locking; cross bars are generally made of twisted square steel, but also round steel. Or flat steel, the material is divided into carbon steel and stainless steel. Ditch cover has been widely used in all walks of life at home and abroad, mainly used as industrial platforms, ladder treads, handrails, passage floors, railway bridge sideways, high-altitude tower platforms, drain covers, well covers, road grilles, three-dimensional It can also be used as a fence for parking lots, institutions, schools, factories, enterprises, sports fields, and garden villas. Steel grating is generally made of carbon steel, and the surface is hot-dip galvanized, which can prevent oxidation. Can also be made of stainless steel. Steel grating has the properties of ventilation, lighting, heat dissipation, anti-skid, explosion-proof and so on. These two installation methods have their own advantages and disadvantages, and you can choose which installation method to use according to your usage conditions. The advantages and disadvantages of the welding installation method of the two installation methods are compared below.

Advantages of welding fixing: 1. Preferential price, no need to purchase additional bolts for fixing, and its cost is naturally lower than the cost of bolt fixing; more durable, extremely high welding temperature, strong bearing capacity, the more welded joints, the stronger the bearing capacity; operation Simple, only hand welding and bolting. Fixing requires aligning the bolt holes, placing the bolts, fixing and tightening.

Disadvantages of welding and fixing: 1. The surface of the welding point is damaged and easy to rust. It is recommended to spray paint after welding and fixing; 2. It is inconvenient to disassemble and assemble, and the welded steel mesh has become a whole; if you want to disassemble and install it easily, you can Select the method of bolting.
