How do I choose the right Profile for my project?
Metal roofing sheets are manufactured from galvanised steel and so do not require treating to protect them from the elements. Any newly cut ends can be painted with a metal paint of a similar colour to help protect exposed metal edges.
Yes, box profile roofing sheets are manufactured using galvanised steel, which has a corrosion-resistant component to ensure a high-quality, long-lasting product.
Cover Width:
- Box Profile Roofing: Provides an effective cover width of 1.000 meters once lapped.
- Corrugated Roofing: Offers a 0.991 meter cover width once lapped.
End Lap:
Both box profile and corrugated roofing systems require a standard end lap of 150mm to ensure a secure, weatherproof seal.
Side Lap:
Each roofing sheet should overlap by at least one complete profile along its length. If you're unsure about the exact measurement, Tinman Steels are here to offer expert guidance.
Roofing Sheets can be used as side cladding, we advise a 0.5mm thickness for side cladding.
Our Box profile sheeting onto purlins is spaced at around 1.375mtrs (agricultural) or 1.500mtr - 1.800mtr (industrial). Tek screws should be fitted in the trough of the profile. On the first and last purlin you would fit 5 fixings and then 3 fixings should be used on all intermediate purlins. 5 fixings should also be used on sheet overlap.
Prices vary depending on gauge, coating and quantity you require. Prices start at £4.35 per linear metre (as of 12/06/2025). We need to monitor the price, as it changes several times a year.
Please use our profile identification form at the top of this page. The dimensions should match your current box profile closely. If you need more help or advice, please call the team at Tinman Steels. They will be happy to assist you.
The minimum pitch required for a single pitch roof differs depending on what Profile Roofing Sheet is being installed.
- Box Profile Roofing Sheets - 4° minimum pitch after deflection
- Corrugated Roofing Sheets - 4° minimum pitch after deflection
- Tile Effect Roofing Sheets - 12° minimum pitch after deflection
No, but you can fix them onto timber purlins. We can supply tek screws specifically for fixing into timber.
You can use any "cold cut" tools to cut our box profile sheeting. This could be a nibbler or an evolution saw with a steel blade.
To prevent condensation we can supply our box profile sheeting with a Drip Stop backing. This is a felt like membrane that is bonded to the back of the sheets. It is designed to absorb moisture and thus prevent condensation from dripping. At temperatures above the dew point, the condensation is emitted into the air again as moisture, and this can then the carried away through appropriate ventilation of the roof. For box profile sheeting you will require a minimum roof pitch of 10°.
Alterations to your roof, i.e. changing the materials, there is often no need for planning permission as it is considered permitted development. However, in some cases, i.e. if you are in a listed building, in an area of outstanding beauty or a national park, planning permission may be required. Before making any changes to your roof we recommend seeking out professional advice.
To ensure your roofing sheets will last for many years. It is recommended to check your roofing sheets regularly and clear away any leaves or debris, and clean any marks or scratches (most marks should be able to be cleaned using soap and water).
