HOW TO CALCULATE THE MASS OF MILD STEEL PLATE & FLAT:
Length X Width X Thickness X 7850KG
Example
For a 10mm plate at 2400mm x 1700mm:
2.4 x 1.7 x 0.01 x 7850 = 320.28kg
For a 200 x 6 flat bar at 1200mm:
1.2 x 0.2 x 0.006 x 7850 = 11.304kg
Note: Most price books have an extra 2.5% added onto the weight of merchant bar as a rolling tolerance.
* Add 2 kg per square metre for Floor Plate.
* To calculate the mass of aluminium:
Length x width x thickness x 2710 kg
* To calculate the mass of stainless steel:
Length x width x thickness x 8000 kg

We stock products in both a black (uncoated) finish, perfect for welding, and a hot-dip galvanised finish for long-term corrosion protection.
Can I buy single lengths?
Absolutely. We cater to everyone from large-scale fabricators to DIY enthusiasts. We have no minimum orders.
What’s the difference between SHS and RHS?
SHS is Square Hollow Section, while RHS is Rectangular Hollow Section. Our team can help you choose the right profile for your project.
