Rear extensions are one of the most common jobs we supply steel for across Liverpool and the North West. Whether it’s a single beam, a goalpost or a full frame, getting the order right first time keeps your build on schedule. Here’s a simple checklist to follow.
1. Get your structural calculations
Your steelwork needs to be designed by a structural engineer. They’ll give you calculations and, for fabricated steel, drawings. Building control will usually want to see these too. Read what size steel beam do I need? for more on this step.
2. Check the details on site
Before ordering, check the key measurements on site against the drawings. If anything doesn’t match, speak to your engineer first rather than changing sizes yourself.
3. Send us your drawings for a quote
Send your calculations or drawings through our upload page. A PDF or a clear photo is fine. Draft drawings are fine for a quote; we’ll need the final version when you order.
4. Confirm what you need
- Section sizes and lengths for each piece.
- Fabrication: cutting, drilling, end plates, base plates or welded connections, as shown on the drawings.
- Finish: raw, primed or galvanised.
- Quantities of each piece.
5. Plan your delivery
Let us know your delivery postcode, the best time to deliver and any access issues, such as narrow roads, parking restrictions or a tight side passage. If you’d rather collect, our yard is on Alexandra Road, Edge Hill. Our delivery guide explains what to expect on the day.
6. Place your order with final drawings
Once your drawings are approved, send the final version when you order. Steel is cut and fabricated to the drawings we receive, so let us know straight away if anything changes.
