How does ordering work?

After you've placed your order, we'll give you a ring to confirm your measurements, delivery location, delivery dates/times and any other essential pieces of information before we begin manufacturing your products. This gives you some time to let us know if anything needs changing before it's too late. Once you're fully happy and have given us the go-ahead, we'll begin manufacturing your joists ready to be delivered for your specified date.

Can I supply more measurements?

Yes—either use the 'order special instructions' box in the basket or send us an email with any specific requirements you may have along with your name and/or order number.

What's the price including VAT?

Simply add your required items to the basket and proceed to the checkout—the price including VAT will be included here.

What are your delivery options?

- Fast Track (5 Working Days)
- Standard (2-3 Weeks)

Both are free if you spend over £2000, or £150 if under £2000.

Is bracing timber included?

Yes—all strongback bracing timber is included in the price above.

Do I need a structural engineer?

No, you don't need a structural engineer. We will design the roof truss and provide you with the necessary structural calculations for building control.

Are your products treated?

As standard, our products are not treated. Treatment is only necessary if you live in the red marked areas on this map. If you do require treatment, please get in touch.

Please note, maximum span refers to the total length of the joist including bearings. Posi-Joists ordered here are intended for domestic floors only or flat roofs with a build up weight not exceeding 100kg per m2. They should be spaced at no more than the centres specified, and should not be used as beams or trimmers supporting other elements. For all other requirements, please contact us for a full design and quotation.
