Welded Stainless Steel Gratings

by Sunj Grating Limited

To make welded stainless steel grates, bearing bars and cross bars are used.

Welded Stainless Steel Gratings
Bearing bars and cross bars are used to make welded stainless steel gratings. Bearing bars are the main load-bearing components of gratings. There are different thicknesses and depths available. A variety of thicknesses are available for the crossbar, which is the secondary load-bearing component of the grating. In order to create a strong and rigid joint, the two types of bars are welded together.

Stainless Steel Grating Process Flow
Make sure the gratings are of the highest quality. There are a few crucial steps in the manufacturing process. The gratings will last a long time if these steps are followed. The following is an outline of the process flow for manufacturing gratings:

Step 1: Material And Construction:

Choosing the right material for the gratings is the first step. The GI-RO technique offers different constructions of grating, each with its own advantages. The materials are selected after deciding which structure to use. Stainless steel and aluminum are the most commonly used materials.

Step 2:Tensioning:

A tight, even surface is then created by tensioning the material. It helps if the surface is not completely flat but slightly curved. It is crucial to avoid distortions in the wavefront and ensure that the grating is flat. A jig or a template is used to tension stainless steel.

Step 3: Stainless Steel Gratings In All Sizes:

GI-RO technique produces stainless steel gratings of all sizes. Using a water jet cutter, cut the gratings to size with the highest quality materials. Thus, the corners are perfectly 90 degrees and the edges are clean and burr-free.

Step 4:Surface Of The Gratings:

The surface of the gratings can be acid cleaned, brushed, or blasted to suit the customer’s requirements. Stainless steel gratings are usually acid-cleaned to give them a bright, shiny finish. A different surface finish can be achieved by blasting or brushing the gratings.

Step 5: Crossbar Welds:

Afterwards, the gratings are welded to the crossbars. It is possible to create very small and precise welds with a TIG welder. Welds are protected by Argon gas, which prevents oxides from forming.

Step 6:Fixing Of The Gratings:

After the gratings are welded to the crossbars, they must be fixed. The gratings are welded or screwed to the supporting structure. Thus, the gratings are securely fastened and cannot be removed without damaging them.

Step 7:End Products:

Now that the gratings have been installed, they can be used! Panels or sheets are available for delivery. GI-RO can also cut gratings to order if the customer needs a specific size or shape.
