You haven't told us what product you are enquiring about here, assuming you are trying to protect steelwork, in order to enable us to provide a specification please provide the following information;

• Level of fire protection required (i.e. 30, 60, 90min, etc.)
• Each steel section dimension (i.e. 254x146x37 UB)
• Quantity and length of each section (or overall meterage for each section)
• Orientation (horizontal or vertical)
• Number of sides to be painted (all sides, 3 sides, 1 flange, etc.)
• Environment (internal, external, car park, chemical exposure, etc.)
• Application on site or in shop

Alternatively you can just forward us drawings, fabrication/cutting lists and we'll extract the information from them but in that instance we'd need some guidance as to what to allow for i.e. all steels on first floor, etc.
