Chequered plate weight calculation guide

Chequered plates are steel flooring used in industrial structures. Normally the maximum spacing of chequered plates are between 1 metre to 1.2 metre. Chequered plate thickness is measured excluding the chequeres. That is to say 6mm thick chequred plate means 6 thick plate with chequres above it. Hence the weight of chequred plate comes higher as compared to plain plates. Weight of chequeres are approximately 6.1 kg/m² over and above the plate weight. Dead weight of chequered plates are as below.

The generalised formulae to calculate weight of chequered plate shall be 

Weight of chequered plate (kg/m²)= thickness (m) x 7.85 (kg/m³) + 6.1 (kg/m²)

If you want to find weight of total plate to be used in project, use following formulae.

Total weight of chequered plate (kg) = Length (m) x Width (m) x ((Thickness (m) x 7.85 (kg/m³)) + 6.1(kg/m²))

The Indian Standard code for chequered plates is IS 3502: "Steel chequered plates". This code specifies the requirements for hot-rolled mild steel plates, sheets and strips intended for use in structural work. The chequered plates are usually made from carbon steel or mild steel and have a pattern of raised diamonds or lines on one side, which provides additional grip and traction. IS 3502 outlines the physical and mechanical properties of the chequered plates, including dimensions, mass, thickness, width, and length. It also provides information on the tolerances, surface finish, and marking requirements. The code also specifies the test methods for checking the properties of chequered plates, including tensile strength, elongation, and bend test. Additionally, it provides guidance on the packing and storage of chequered plates. IS 3502 is an important standard for the manufacturing and usage of chequered plates in India and is widely used by manufacturers and users of these plates.
