We convert every weight — round, square or rectangular, in any mass — to a single price per kilogram. That’s the one number that lets a 20 lb piece be compared fairly with a 36 lb one.

Both. Use the inc/ex VAT toggle on the comparison table. Trade suppliers usually quote ex-VAT and consumer shops inc-VAT, so we hold both and let you switch.

Supplier retail prices are re-checked weekly. The lead spot (LME) price in the header refreshes daily, so you can see how the raw-metal cost moves against finished-product prices.

No — prices are product-only so sizes compare like-for-like. Where a supplier’s delivery or carriage materially changes the deal (e.g. a charge on small orders) it’s flagged on that row.

Yes — email [email protected] to be added to the comparison table.
