There are many vision panel sizes and designs available, however, there are restrictions for fire and sound rated doors.

Finish Options

PuraSteel doors can be supplied primer finished, powder coated or wet spray finished to the RAL colour of your choice. We will support you in the co-ordination of finishes with other elements of your project. Please ask for a sample to help you achieve the colour and finish you desire.

Packaging & delivery

Steel doorsets are usually supplied in a single package to protect security features. Exceptional care is taken with packaging to ensure the products you open on site are exactly as they were when they left us. Depending on the specification, some elements may be individually wrapped and for larger orders they may be carefully stacked. The whole is then fully encased in a protective wrapping.
