Square Bar Weight Chart in KG, MM, PDF


The Square Bar Manufacturer is the producer of square bar of various sizes, lengths, and materials to suit the needs of industrial, construction, and engineering purposes. Square Bar Weight Chart in KG, MM, PDF is a reference useful to the engineers, contracters and the procurement professionals in the planning of projects, estimating of materials and purchasing. In building structures, machinery, automotives, and manufacturing, square bars are commonly used. Manufacturers also offer specialty bars like the Aluminium Bronze Square Bar and Stainless Steel Square Bar to meet the demand of corrosion resistant and high performance.


This offers the Square Bar Weight Chart that gives extensive details on the dimensions of bars, cross section and weight per meter across all sizes and materials. Square bars are sorted by the material type (carbon, alloy, stainless, and aluminium bronze) and international standards (ASTM, DIN, EN, and IS). These bars are highly stronger, durable, corrosive free, and long-serving, which makes them very suitable in structural, mechanical and industrial purposes.
