We typically stock merchant bar in standard 6 meter lengths. However, through our in house sawing and cutting facitilies, we provide precision 'cut-to-length' services, ensuring your material is ready for immediate fabrication. 
General Facts
The industry standard grades for the merchant bar in the UK are S275JR and S355JR. S275Jr is the most common grade and most common choice for general welding and fabrication. S355JR is specified for the projects requiring a higher yield strength, allowing for a stonger structure without a significant increase in the weight of the steel. 
Merchant bar is weighed by the Kilogram per metre (kg/m). The total wieght of an order is determined by the cross-sectional area of the profile multiplied by the total length. Accurate weight data is essential for site safety, crane lift, planning, and vehicle loading. 
Merchant steel, or merchant bar, referes to a catagory of long steel products used by fabricators. This includes Flats, angles, rounds, and squares. Unlike heavy structural steel sections (like universal beams and columns), merchant bars are typically smalles sections used for bracing, secondary steelwork, and general manufacturing.
