The Process of Metal Truck Scale Production 

Metal Truck Scale

It is obvious that producing a high-quality truck scale needs to be planned based on international provided standards like OIML, NIST and NTEP. To apply all regulations and requirements, it is necessary to do all implementations as like as requirements are mentioned in these standards instructions. The quality control department is responsible to follow the production process of a truck scale to meet all needs. 

The quality management system draws the overall path of production in all companies and organizations. At Pand Caspian Company, we do all production process under the quality management system orders, and this is also being implemented in the production of metal truck scale. This article explains the production process of metal weighbridge.  

STEP 1: Purchasing High-quality materials

Purchasing well-made raw materials is the primary and essential step of production process. The use of flawless raw materials in the mass production of metal truck scale is the main reason of its long lifespan. Metals pass various stages from mining to recovery in purpose of becoming steel, in which each tiny mistake can lead to poor quality. As truck scale especially Metal Truck Scale is a sensitive product, tuck scale manufacturers have to evaluate the quality of purchased metal before being used as truck scale platform or as any part of truck scale construction.

We made some quality control forms in which all materials should be evaluated based on standards. The purchase of welding rod, color and other items are also mentioned in detail on purchase forms.

STEP 2: Cutting and bending of metals

The raw materials are produced based on what dimensions and sizes is needed for market. To produce a metal scale with platform dimensions of 8 x 3m, steel plates must be cut in desired dimension.  

On the other hand, the rebars and angles used in the scale should be cut and bent based on technical maps. All these steps are carried out by experts under the supervision of a quality control expert. In order to improve the quality of the truck scale, dimensional control and visual inspection are carried out in all stages of cutting and bending. The next step is to assemble the metal scale using welding.

STEP 3: The welding stage of metal truck scale

At this stage, according to the WPS document, in which all welding specifications, including the welding angle and heat treatment before and after welding, are mentioned, the assembly of the metal weighbridge are done. All welders are evaluated by WPQ test and experts are selected for plate welding. After each stage of progress, weld beats are visually and ultrasonically tested by the quality control experts.  

After that, final evaluation is done and it goes to next stage, sandblasting and painting.  

STEP 4: The stage of sandblasting and painting of the metal truck scale

In sandblasting, the main goal is to clean the metal surface and prepare the surface for better color absorption. This step should be done with special delicacy and precision, so that the surface has a thin layer of roughness because metals will have better color absorption.

 The first color layer (primer), which is important and vital, is painted using rich zinc colors. This infrastructure makes the truck scale resistant to corrosion, which increases the health and longevity of the metal scale in the open air and in exposure of rain and moisture. The next layer is painted with a paint containing polyamide. This paint has high adhesive strength and protect the truck scale against scratches and chemical components. Finally, the last layer is painted using polyurethane paint, which protects both layers from contamination.  


Production of metal truck scale has high sensitivity in material selection, welding and painting process. All these steps are carried out in Pand Caspian Technology Company based on material selection and quality control documents.

All stages are done under supervision of quality control experts. Remember that the health and safety of the products are the main priority of our team.
