It is important that accessories used with cladding and cold rolled products be of good quality to support the performance of the component, and not detract from it. We advocate the use of premium quality fixings, fillers and sealants and stock a range of quality accessories at competitive prices. If you require accessories not listed on this website, contact us for more information.

Economical, safe and efficient solution for new build, double skin projects. Our
Support Bar System is equally suited to over-cladding applications, offering a
convenient alternative to traditionally expensive re-roofing jobs.
Complies with the latest ‘part L’ building regulations for side cladding and roofs. The system comprises of a steel liner sheet, galvanised support bracket and ribbed bar together with the external weather sheet. It provides a strong roofing and cladding support system and is fixed to purlins, making it quick, easy and safe to fix.
The bar is 1.25mm gauge Z39 high tensile galvanised steel to EN 10147. The bar incorporates a spigot end arrangement for bar connection and also ensures a continuous level of support. They are manufactured in 1m and 3m lengths.
The brackets are manufactured from 1.6mm gauge Z39 high tensile galvanised
steel with stiffening ribs. Bracket sizes range from 60mm – 250mm.
- Strong, lightweight support system, using a minimal number of
components which makes specifying, ordering and installation easy.
- Faster to install than mini Z's and ferrules, no special tools are required.
- Ideal to overclad failed roofs, quickly and easily.
- Warrington Fire Research 4 Hour certification and excellent insulation potential.
- All components are galvanised which will provide many years of use.
The system can be used with or without insulation. It is not required to remove old or existing roofing materials. It can be used to overclad failed roofs or bring roofing systems up to insulation regulations. It is ideal for new build, twin skin construction.
Although sway bracing is not required, care should be taken to avoid point loads during loading out operations.
Gridtite has Warrington Fire Research 4 Hour certification. Bars weigh 1kg per L/m and can be used vertically, but in this case the bar must be supported at the base to transfer to transfer loads to the sub-structure.
When used in a twin skin situation and purlins are set at 2 metre centres using 0.40 w/w k insulation quilt, the system will achieve the following U values:-
0.25 with 170mm thick insulation
0.30 with 140mm thick insulation
0.35 with 120mm thick insulation
For further information and to enquire how this system could be the answer to your complex overclad requirements, contact us.
Rooflights used effectively can promote a naturally light environment whilst not reducing the insulation, water proofing or stability properties of the system. Our rooflights are manufactured from GRP material which complies to BS4154, ensuring consistent performance. They are kept in stock in both Class I (fire rated) and Class III grade (exterior use). In the case of Class I sheets, the fire rating will be shown by the use of a coloured thread.
Available Profiles: Complete range of box profiles
Class Availability: Class I, Class II
Material Finish: GRP
Standard Lengths: 2.440m, 3.048m and 3.657m
A range of grade weights and lengths are available on request. Contact us for further information.
Diagonal ties are used as a bracing on the lower level of side rail runs. The tie wire is fixed on the lower side rail using a bottom tie brace bracket, which itself is fixed underneath the vertical strut. The tie wire is then fixed to the bottom of the upper side rail with a top tie brace bracket. Tie brace brackets are available in single or double configurations.
Used to stabilise Z-purlins, anti-sag rods and apex ties are an essential component of the roofing support system. Without these, Z-purlins with the force of weight they hold would give way and bend. The support that is offered by these two components effectively minimises the horizontal movement of the Z-purlins over the lifespan of the roofing system.
Use this calculation to derive the length anti-sag rods required;
A = Purlin centres (A²), B = Sag Rod hole centres (B²)
A² + B² = C²
VC² = Rod length between purlins
VC² + 64mm = Production length
We have a range of vertical struts to suit different situations. The overall length of the strut will depend upon the centres of the side rails. Brackets are held in stock for different section sizes of side rails.
Rafter stays are utilised (as per the diagram) to provide the support system with more rigidity. Rafter stays are fixed to the bottom sides of the C-section sleeve and then to a cleat on the main hot rolled rafter. We have a range of sizes available in stock, as well as manufacturing to custom specification.
A large range of fixings are stocked for use with our profiled steel cladding and cold rolled products. Fixings are normally positioned in every other support across the width of a profiled sheet. In exposed conditions, extra fixings would be used.
Follow the below recommendations to maximise stability and minimise cost. Please note that these recommendations do not apply to all situations, if in any doubt or in need of assistance, contact us.
- Side laps are stitched at 450mm centres and end laps at 150mm.
- If the roof pitch is less than 15 degrees, the end lap stitching could be increased to 200mm.
- If the roof pitch falls between 7 and 4 degrees it is recommended to use sealants on both sides and lap ends.

A wide range of specialised tapes and sealants are available on request. Our team will be able to advise on your specific situation.
A range of durable, deterioration resistant vapour barriers are available, reducing the degree of condensation and eradicating the risk of water ingress. Foam fillers are manufactured to suit all our profiles, are formed in both long and short flutes and are used to reduce draughts and vermin entry.
NOTE: The use of our fillers is recommended to ensure a snug fit to Hayes E&C Ltd’s range of profiles.
