We are proud that we have been able to offer a 5 working days delivery service, for the past 39 years.

The estimating department will prepare a detailed, itemised quotation listing all the items that you require for your project. This is usually all roof trusses, stability bracing (100x22), timber to timber metalwork and all structural loose timber above wallplate.

For engineered floor joists quotations it will include floor joists and any hangers for connecting the joists will be included. We can also provide a price for stud wall noggins, perimeter noggins, z-clips and safety fast joist end caps on request.

The quotation that we prepare you includes for the delivery of the order to your site address.

Drawings of every truss and layout setting out drawings are supplied with the itemised detailed roof truss quotation. The quotation and drawing service is supplied to yourselves, free of charge.

A copy of calculations for roof trusses can be supplied (upon placement of an order) to yourselves or direct to building control.

Yes, we can supply products that have been treated with Protim, which is a water based environmentally and human friendly preservative.

We also stock cans of Protim's cut end preservative which you will require once you have cut your loose timber on site. This is easily brushed on the untreated ends of the timber.

To help speed up your installation of your roof on site, Minera Roof Trusses can on request, also supply you prefabricated items made ready for quick installation on site. These include gable ladders, valley sets, spandrel panels, prefabricated dormer trusses and versalam beams.

Minera Roof Trusses can also supply you with bolts for girder trusses and square twisted wire nails for your metalwork and Glide Shoes, a metalwork connector for raised tie trusses.

The project controller can check the measurements that we require for each truss span and mark the alterations on the quotation form, or directly onto the truss profile drawings that we sent you along with the quotation.

If there is a significant difference, then you can send in a new set of drawings and we can reissue the revised drawings to suit the new site dimensions.

We offer a site survey facility for locations within 75mile radius of our factory, on payment of a fee.

Ordering with Minera Roof Trusses is simple. You can telephone us and let us know that you wish to order. Our friendly and helpful staff will then be able to guide you through the process.

Or if you wish, you can sign the documents that you have received with your quotation and return them to ourselves with payment in the form of one of the options detailed below.

And we now are able to receive a 256 bit encrypted email with your payment details submitted direct to our order department at any time, 24/7.

Minera Roof Trusses accept payment for your order via Maestro, Visa Debit, Electron, Solo, Mastercard* , Visa* , Direct transfer to our account via CHAPS or BACS, cheque or Cash delivered by hand to our reception.

Our deliveries are scheduled by our production manager to determine a day for your delivery which is 5 working days from when you place your order. If you do not require them that soon, then please let us know when placing your order.

If you need the delivery to arrive to meet a crane on site, then please let us know when placing the order.

The production manager may send you a transport request form to let you know how many persons will be required on site to meet our wagon, or whether you will need a crane or telescopic fork lift truck to unload heavy and awkward shaped loads and to enquire about site access restrictions.

If you need to know the time for your delivery, you can give us a call on the day before, and we will then have a good idea as to what time your delivery should be with you.

Yes; we were one of the founder members of the Truss Rafter Association (TRA) formed to represent the interests of the pre-fabricated roof truss industry, which only permits membership to manufacturers who have the highest standards of Quality Assurance and a specified level of Professional Indemnity Insurance.

Minera Roof Trusses are ISO 9001 Quality Assured.

Unfortunately, no alterations can be carried out to any truss without consultation with Minera Roof Trusses.

We have had the question asked many times before. My electrician is running a few wires along my roof can he drill holes in the timber to feed the wiring through? Can I cut my roof trusses? Can I drill a hole in the trusses to fit the plumbing through?

Usually we get the question asked AFTER they've done it. Thats TOO LATE!

Again, Never cut, drill or alter trusses. They are designed specifically to support your roof and it is a complete unit. Making any alteration, cutting or drilling is drastically altering the way the forces are transferred into the timber and plates. Doing so will invalidate the design of the trusses.

Any work that may alter the structure at a later date should of be discussed with Minera Roof Trusses BEFORE the manufacturing process has begun, ideally when the project is in Order Stage.

Occasionally it may be possible to carry out a remedial detail on site to the affected roof trusses by our Engineers and there is likely to be a cost involved.
