1000 x 25mm TEK SELF DRILLING METAL ROOFING SCREWS TO LIGHT STEEL 8mm HEX HEAD. This listing is for a box of 1000 25mm long screws for fixing roofing sheets to light steel supports or zed purlins up to 3mm mild steel thickness. The technical code is LS25-S19 or M5.5 x 25.

These are superior screws as they are made from hardened C1022 Steel which is zinc anodized, rather than chromium plated. This offers increased corrosion and wear resistance and provides better adhesion for paint.

They are fitted with a stainless steel and neoprene rubber sealing washer and have a drill-point tip for drilling and self-tapping through the metal purlin. The screw head is 5/16 / 8mm.

We can supply TEK screws in various lengths from 22mm to 150mm to wood and steel. We can also supply plastic colour caps to cover the screw heads. We also have a vast range of Roofing, WPC Decking, Fixings and Accessories available in our shop. Please note images may vary from actual item supplied due to lighting variations and camera angles. For larger items such as trims, several packets of fixings etc, we use Parcel Force. For Roofing sheeting & decking orders we offer a free collection from our premises in Okehampton Devon. Or we can deliver to UK Mainland using our Cladco Trucks. If the vehicle is invited on to the customers property it is entirely at the risk of the customer, Cladco Profiles and its drivers will not be liable for any damage to the property. Our drivers will generally call you before they arrive at your site. We use medium sized lorries of up to 18 tons. Any issues should be immediately reported to us by contacting our Customer Service Team. The edges of sheets and flashings can be sharp so remember to wear suitable protective gloves with rubber palms for grip. We do not recommend installing your deck in cold weather. Your composite decking boards can be worked with normal woodworking tools. We recommend using a wood saw with a fine-tooth blade to cut boards to size. When cutting, care should be taken to ensure that boards are properly supported. As with other building work it is important to work safely and to take suitable safety precautions including the wearing of protective clothes, gloves, safety goggles and dust mask. 1: Build a supporting substructure. Make sure that the base is flat and stable. Decking boards must not be laid directly on the ground but should be fixed to joists of a suitable supporting substructure. This will vary, for a domestic patio deck we typically recommend a simple concrete base and our own WPC joists. The concrete base should be at least 10cm thick and have a slight slope we suggest a gradient of 1 in 40 that runs away from the property to allow for the run-off of water that collects under the deck. The WPC joists should be fastened to the concrete base using screws through the joists and plastic raw plugs in the concrete base.

They should be fixed so as to create parallel, regularly spaced rows in-line with the slope of the concrete base, again to allow for the run-off of water. The maximum recommended space between joist rows depends on the angle at which you intend to lay your boards in relation to the joists, but should never exceed 40cm , please see diagram below.

A gap of at least 8mm should be left between the ends of joists and a fixed object such as a wall and of at least 10mm between the ends of joists at butt joints. These allow for proper drainage and temperature expansion. Remember the suitable supporting substructures for your deck will vary with the circumstances. If you are unsure contact our Customer Service Team.

2: Fix decking boards to joists. Our composite decking boards are easily fastened to the joists of a supporting substructure with the help of our stainless steel screw and plastic T-Clip system.

Start at the outside of the area to be decked. Place your first board and screw it into each joist it crosses with a countersunk decking screw of suitable length.

Then fit T-clips into the groove along the side of the board and screw them into each supporting joists with the screws provided, one T-Clip for each supporting joist. Fit your next board by sliding it onto the T-Clips used to secure the first board and fitting another set of T-Clips to secure the opposite side of the board, again one T-Clip for each supporting joist. Follow a similar process to fix subsequent boards attaching the final board in a similar manner to your first. As an alternative to using T-Clips, our boards can also be screwed straight into supporting joists using decking screws through the center of each board.

Unlike timber, composite decking only requires one screw in the center of each board as they do not warp or bow. Decking boards must be properly supported! The ends of boards must be fully supported. No overhang or cantilever is allowed. At butt joints where the ends of two decking boards meet, this may mean doubling up on supporting joists.

It is recommended that a gap of at least 7mm is maintained between the sides of adjacent boards to allow for drainage and expansion due to temperature increases. The use of plastic T-Clips helps ensure these gaps are maintained.

Gaps of 8mm at butt joints where the ends of two boards meet, and of 10mm between the edges of boards and objects such as wall should also be observed for similar reasons. Having fastened your boards all that remains is to tidy up the sides of your new deck with our WPC skirting and corner trims which can be used to hide the unfinished end of boards and supporting joists.

Our skirting trims can be screwed directly into joists with wood screws. A gap of at least 8mm should be maintained between skirting trims and the ends and sides of boards to allow for expansion due temperature increases. Corner trims can be applied subsequent to skirting trims to achieve a finishing touch by screwing them directly into decking. We recommend that you do not fully close your deck to allow for the free circulation of air and drainage.

Q: Does the composite decking have a guarantee? Q: How much does the composite decking cost?

A: Our decking is extremely popular due to our very low and competitive pricing. Q: What colours does the composite decking come in? A: The decking boards are available in 5 colours; Light Grey, Stone Grey, Teak, Coffee and Charcoal. Decking images showcasing each colour can be found on individual product pages, however if you would like to get a better idea of these you can order a sample pack here. Q: How do I install the decking?

A: Please refer to our installation guidelines here. Q: How far apart should the supporting joists be? A: The supporting joist below the composite decking boards should be a maximum of 400mm apart. For further information on installation please see our installation guide. Q: Do I need specialist tools to install the decking?

A: There are no specialist tools required. The decking can be installed using the same tools you would use to install timber decking. Q: Which type of sheet is right for me?

A: Depending on building type, use and appearance, we manufacture and supply 4 different types of profiled sheeting, all of which can be supplied to the exact length necessary in a choice of colours, with complimenting roof lights, flashings, fixings, fillers etc. What width do the sheets actually cover when lapped on the roof? The 34/1000 profile sheets actually cover 1 metre and our corrugated covers 990mm. How much should each sheet be lapped? Just 1 corrugation or profile.

However, you may want to lap more corrugations or profiles on the last sheet of the run so the last sheet does not protrude over the end of the roof. When using TEK self drilling screws, do you fit them on the top or the lower part of the sheet profile? We advise the lower part on box profile. They have a neoprene washer below the screw head to prevent leaks and as long as the screws are fitted square, there should be no leaks.

If the screws were fitted to the top of the profile the profile and sheet would distort as the screw is tightened. The Corrugated we still advise fitting through the top. What are the minimum and maximum lengths sheets can be made to? Minimum length is around 750mm, maximum is around 9 metres, however please call our friendly sales team on 01837 659901 to discuss any custom sheeting requirements.

Is there any minimum order size? Please call our sales team or send us a message to discuss your order.

What do the sheets weigh? They tend to vary according to sheet thickness and width but in general a 3m sheet will weigh approximately 18kg. Q: How do I install the roofing sheets? This is also referred to as you, or your, below.
