We deliver across mainland UK, fully tracked. Other areas, and projects abroad, are on request: contact us before you order and we quote the delivery.

Yes, on request. Our online shop delivers across mainland UK. For a project abroad, contact us and we quote the supply and the delivery.

Very large or heavy orders may need bespoke freight. If yours does, we contact you with the options and the cost before dispatch. Every order is sent tracked, and an order may arrive in more than one delivery at no extra cost.

Please give us a complete, accurate UK address and make sure someone is available to accept and sign for the goods. We recommend an established, staffed address and advise against unattended or unnamed sites, such as a construction site with no clear address. If a delivery fails because of an incomplete address or no one being available, a redelivery fee of £15 per attempt, or the cost of re-shipping, may apply. See our Shipping Policy for details.

Every order is sent tracked, and the tracking link is in your shipping confirmation email. If your order arrives in more than one delivery, we share tracking for each where it is available.

Yes. Credit accounts are available to established trade customers after a first order, on application. Contact us to apply.

Yes, for large project orders we offer bespoke pricing outside our standard website prices. Send us your fixing schedule or bill of materials and we'll provide a competitive project quote.

Yes, every order comes with a full VAT invoice. Our VAT registration number is GB 489884695. We are UK VAT registered.

Yes. We lead connection design for mass timber, CLT, glulam and timber frame, working with our engineering partners. Whether the design comes with liability cover, and who signs it off, is agreed with you case by case. Send us a drawing and you get an initial reply within one working day.

Eurocode 5 (EN 1995) is the European standard for designing timber structures, and in the UK it is used with the UK National Annex. Design work we lead is delivered with our engineering partners, to Eurocode 5 and the requirements of your project. Our guide, Eurocode 5 explained, covers the basics.

Yes. Connection design for CLT, glulam and timber frame is at the centre of what we do. We lead it with our engineering partners and come back with the connection detail, the products and the quantities. In CLT, the panel manufacturer's own approval also sets rules for the fixings, so the design follows whichever of the two is stricter.

Yes, through our engineering partners, where it is agreed for your project.

Engineering is quoted per project, once we have seen the drawing. Contact us for an estimate.

Yes. Use Send your drawing: a drawing, a sketch or a phone photo is enough, and you do not need the product codes. We send an initial reply within one working day. Product codes, quantities and pricing follow once we have enough project detail. We work to your engineer's drawings and loads, or lead the connection design with our engineering partners if you need it.

Yes, per project, through our international supply partners. Tell us about the project and we come back with the options. See mass timber sourcing.

Yes. We are the UK point of contact for TimberTech Buildings, structural design software for timber developed by TimberTech in Italy. We arrange demos and trial licences. See TimberTech in the UK.

Yes. The technical datasheet is linked on the product page. The Declaration of Performance comes from the manufacturer, and where a product also has a European Technical Assessment, that is issued by an independent assessment body. Ask us and we send you the ones that apply to your products.

Where a product has a Declaration of Performance, it carries CE marking, and CE marked construction products can be placed on the market in Great Britain. We answer product by product, so ask us about the one you need.

Screws and metal connectors carry a reaction to fire class, which describes how the material itself behaves in a fire. The steel in our assessed structural screws, angle brackets and hold-downs is classed A1, the non-combustible class. Fire resistance is a different thing: it belongs to the whole joint and the structure, so it is settled in the connection design, which we can lead with our engineering partners.

Start with your post: its shape and size. Then what you are fixing to, a slab, a footing or soft ground, and whether you want a fixed or adjustable height. The post base selector filters by post shape, size, mounting method and finish, so you only see the bases that fit.

Yes, for most garden fences. On an existing slab, path or patio, use a bolt-down post base. On soft ground, use a base that anchors or drives into the ground. Both keep the timber clear of wet soil. Our guide, How to fix fence posts without concrete, explains when concrete still makes sense.

Our fastener calculator works out the screws, dowels and anchors for each connector at its full fixing pattern, in box quantities. It does not calculate spacing. Minimum spacing, edge and end distances come from each screw's datasheet and approval, and they change with the screw diameter, the timber and whether you predrill. Our spacing guide explains how to read them.

Zinc-plated screws are for indoor use and for sheltered spots that stay out of the rain. Outdoors, use stainless steel or a screw with a coating rated for outdoor use. Near the coast, in oak and other acidic timbers, and in treated timber outdoors, the demand goes up, so choose a fixing rated for that exposure: stainless steel, or one of the coatings made for those conditions. Indoor pools are the hardest case of all, and only the highest grade of stainless steel is suitable there. Each product page shows what the screw is rated for, and our guide, Stainless vs coated screws, explains the difference.

It depends on the timber's density, the screw's diameter and the screw itself. Most structural screws go into softwood without a pilot hole. In dense hardwoods such as oak most screws need one, but some screws are made to go into hardwood without predrilling. The screw's datasheet gives the limit, so check it before you fix.

A partially threaded screw is mainly for shear, where the load crosses the screw. Its strength comes from the timber bearing on the screw and from the screw bending, so it grows with the diameter, and the joint gives a little before it takes the load. A fully threaded screw is mainly for loads along its length. The whole thread grips the timber, its strength grows with the threaded length, and the joint is much stiffer. That is why fully threaded screws are set at an angle for high-load connections and used to reinforce timber.

They are three separate scales. SC is the service class: how damp the timber gets in use, from dry and heated indoors to wet or in the ground. C is how corrosive the air is around the part of the fixing that is exposed, which rises near the sea, near salted roads and in polluted areas. T is how aggressive the timber itself is to the part of the fixing inside it, which depends on the species, any treatment and how wet the wood gets. A fixing suits your job only where it is rated for all three.

It depends on how you fix the boards. If you screw through the face of the board, the usual UK guidance is two screws at every point where a board crosses a joist, set about a quarter of the board's width in from each edge. If you use a hidden clip system, the count comes from that system's own installation guide. Our guide, How many decking screws do you need?, shows how to work out the total.

Open on the outside, closed on the inside. The breather membrane goes on the outer face: it keeps rain out and lets water vapour escape, so the wall dries outward. The vapour control layer goes on the warm inside face and limits how much moisture gets into the wall. Our breather membrane guide covers choosing and fitting.

Match the hanger to the joist's width and depth, and to what it fixes to. The datasheet gives the load for each size and the fixings it needs. Our guide, Timber joist hangers, covers the types and how to fit them.

Keep the panels dry from delivery until the building is enclosed. Plan deliveries so site storage is short, keep the factory wrapping intact, and store the panels on clean supports well off the ground, in the shade and away from splashing water. Seal the end grain at panel edges and openings, tape the panel joints straight after installation, and get the weather protection on as early as the programme allows. Timber Development UK publishes guidance on moisture during construction.

Some Rothoblaas products have an Environmental Product Declaration. Ask us about the product you need and we send it where one exists.
