Thickness and sheet sizes
Choosing the
right sheet
The hole pattern decides how the sheet looks, while the thickness and sheet size affect its strength, weight and how much cutting is needed. If you’re not sure, tell us what it’s for and we’ll suggest one.
Thickness
Stainless 304 patterns come in 0.4mm to 4mm. Most of what we keep on the shelf is 1mm to 3mm.
Each pattern page lists every thickness it comes in and which ones are on the shelf.
Sheet sizes
Sheets come in three sizes, though not every pattern comes in all three. Buy them whole, as part sheets, or cut to your exact sizes.
Fewer cuts usually means less waste, so it’s worth telling us your finished sizes up front.
Open area
Open area is how much of the sheet is holes. More open area lets more light, air and sound through; less keeps the sheet stiffer and more private.
The same 5mm hole can look very different depending on the pitch.

FAQ
Can’t see your question? Ask us. Our sales team can check stock and sizes.
What thicknesses do you hold?
Most stainless 304 patterns we keep on the shelf are 1mm, 1.5mm, 2mm or 3mm. The full range runs from 0.4mm to 4mm. Each pattern page lists every thickness and which ones are on the shelf.
What sheet sizes are available?
Stock sheets are 2000 x 1000mm or 2500 x 1250mm. We can get 3000 x 1500mm in to order, usually in 5 to 7 days. We can cut part sheets or exact sizes from any of them.
What’s the difference between 304 and 316?
316 has molybdenum added and 304 doesn’t. We stock both. If your drawing or spec names a grade, pick that one, or ask us.
How quickly can I have it?
Full sheets from stock go out the next working day across the UK. Cut pieces and made-to-order patterns get a delivery date when we price them, usually 5 to 7 days.
Can you cut it to size?
Yes. Send us the sizes and quantities, or a drawing, and we will price the cutting with the material.
Do you have a minimum order?
No minimum on stock sheets. Ring or email the sales office and we can check stock and price it.
