  • Box profile steel cladding (or trapezoidal) is a modern alternative to the traditional corrugated metal sheets and is most commonly used on industrial and agricultural buildings, however it is also used domestically as well. Rather than the rounded corrugations it has 'angled' ones that give it more of a modern look.
  • The 1000/32B Grey Alkyd sheets are a cheaper 'non-prime' sheet. They have a grey primer on the outside of it, so there is no plastic or polyester coating and the underside of the sheets could be a mix of different colours & finishes. These cheaper sheets could be great if you have a small project where the inside is not visible or it doesn't matter about consistent colours. Also, the primer is OK to paint on.

  • What do our box profile sheets cover when fitted?

  • What part of the sheet do I fix the fixing screws? 
  • As per the MCRMA, you fix box profile sheets in the valley of the profile and not at the top of the corrugation. The washer provided on the fixings when compressed correctly provide a perfect water seal.

  • What is the minimum pitch required for these sheets? 
  • We recommend you do not go any lower than 5°.

  • Can Southern Sheeting cut sheets? Southern 
  • Sheeting will not cut our stock sheets so you will have to organise a way to cut them yourself. We can order sheets in cut to length if needed, please contact our sales team to make an enquiry.

  • What can I use to cut the sheets?
  • The best tool to use to cut these sheets would be a nibbler, you can also use a circular saw if you have the suitable steel blade. Angle grinders are very common to use but you can risk causing rust on the cut edge due to the heat generated from the grinder. Make sure the cut end is tucked under the ridge flashing or overlapping sheet. 

  • How much should I lap these sheets by? 
  • For the box profile sheets, you want to lap them by 1 corrugation. If you are using multiple sheets down the run, the minimum end lap on these sheets is 150mm. 

  • What do the sheets weight? 
  • These sheets weight 4.8kg square metre. 

  • What care and maintenance are needed for these sheets? 
  • You should inspect your roof every year to make sure there is no build up of debris such and branches, leaves, nests etc. If there are any markings, regular cleaner and water should suffice. 

  • As these sheets are non prime quality, can I pick sheets with all the same colour underside? 
  • No, unfortunately we do not allow this. Non prime sheets are sold as they come from the pack. 

  • Can I use these sheets for side cladding?
  • Yes, these sheets are fine to use for side cladding.
