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

Aluminium patterns come in 0.7mm 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 edges drawn to scale. Dark bars are the thicknesses we hold most often.

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.

The three sheet sizes, drawn to the same scale.

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.

Reading a code

R5 T8 means 5mm round holes on an 8mm staggered pitch. C means a square hole, U means holes in straight rows, and LR is a slot.

Call 0117 963 4579Email us
What thicknesses do you hold?

Most aluminium patterns we keep on the shelf are 1mm, 1.5mm, 2mm or 3mm. The full range runs from 0.7mm 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.

Can you powder coat aluminium?

Yes, in any of 150 RAL colours. We can cut and fold the sheet first, then coat the finished parts.

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.
