Questions

How much extra should I order?

We suggest about 10% extra to cover cuts and mistakes.

How does it ship?

Orders take 2-3 days to process, then about 3-4 days by ground or 4-6 days by freight. .025" sheets usually ship rolled in our custom boxes by ground. Want them shipped flat instead? Ask us, or choose LTL freight on a wholesale order. Sheets .045" and thicker ship flat on a custom pallet and are not eligible for free shipping. Flat pallets need a forklift or loading dock, or you pick up at the nearest freight terminal. Trims up to 8' ship by ground in a tube or bundle. Free shipping on orders over $600 of embossed .025" sheets, aluminum trim, or corner guards up to 7'10" long. .045" and thicker sheets are not included.

Can I pick up?

Yes. Pickup is 10 AM-5 PM by appointment at Unit 107, 13200 W 43rd Dr, Golden, CO. Web pickup orders are usually left in the shed in front of the shop, which you can open 24/7 with a code we send you.
