Q235 Steel Metal Driveway Drainage Grates Hot Dipped Galvanized
Q235 Steel Bridge Hot Dip Galvanized Anti-Skid Steel Driveway Grates Grating
Steel Driveway Grates Grating Introduction
Steel Driveway Grates Grating is also called platform steel grid plate, platform grid plate, is made of flat steel in accordance with a certain distance and cross bar arrangement, and welded into a kind of steel products with a square grid in the middle, mainly used to do the ditch cover plate, steel structure platform plate, steel ladder step plate, etc.
The bar is generally made of twisted square steel.
Platform steel plate is generally made of carbon steel, hot dip galvanized surface, can play a role in preventing oxidation.
It can also be made of stainless steel.
The steel grid has the properties of ventilation, lighting, heat dissipation, anti-skid, explosion proof and so on.
Two: the classification of the platform steel grid plate:
According to the welding method, it can be divided into: pressure welding type platform steel grid plate, embedded type platform steel grid plate, through the lock type platform steel grid plate and through the welding type platform steel grid plate.
The shape of the side surface of the load flat steel can be divided into: flat type steel grid plate, tooth type steel grid plate and "engineering" type steel grid plate, etc
According to its use can be divided into: general purpose steel grid plate and special purpose steel grid plate such as: trench cover plate, step plate and so on.
Three: the production method of the platform steel grid plate:
Pressure welding steel grid plate is made of load flat steel and cross bar according to a certain distance by adopting 200 tons of hydraulic resistance welding automation equipment welding into the original plate, after cutting, opening, wrapping and other processes and products customer requirements.
Load flat steel spacing: the center distance between two adjacent load flat steel, commonly used 30MM, 40MM and 60MM three.
Rod spacing: the center spacing of two adjacent bars is usually 50MM, 100MM, two kinds.
Our company can also be customized according to customer requirements of various types of steel plate
