Add Mitre Cut
Angled cut to your specification
Mitre cuts can be between 25 to 89 degrees. Cut start height is measured up from the bottom of the member.
Mitre cuts add approximately 1 working day to the standard lead time.
From the beam end to the top of the cut.

Add Bearing Plates
Separate support plates below the beam
Separate bearing plates sit underneath the beam. Multiple plates are stacked together at the first support position.
Spacer Tubes
Included with every paired section
Choose welded spacer tubes on the left member or loose spacer tubes. Overall width starts at the minimum, with the two members touching.
Staggered centres must be at least one third of the section height from the top and bottom edges.
Copy the hole diameter from your connection drawing (e.g. 14 or 18), not the bolt diameter. Leave blank if unsure; confirmation is required before fabrication.

Back to back channels are two parallel flange channels which are bolted together. Their spacing apart means that a cavity can be left clear. Online cut lengths for back-to-back channels range from 1,000mm to 7,500mm.

Choose your section size and enter the required cut length in the order builder, then select the available finish and fabrication options. Review the specification and displayed availability before adding it to your order. Eligible simple beams ordered by 11am can be ready the next working day. Other standard orders typically take 2–4 working days. Finishing and fabrication requirements can extend the lead time; check the date shown in the order builder for your selected options.

Select the required cavity spacing and available hole options in the order builder. Contact the team if the required arrangement is not available.

If you would prefer to discuss your order with our experienced team then please contact the office on 0118 9757500.
