Questions
How much extra should I order?
We suggest about 10% extra to cover cuts and mistakes.
Can you cut sheets to size?
Yes. Custom cuts are $23 per cut, straight 90-degree cuts up to 10' long on our Niagara 10' shear. Enter your sizes in inches in the cut calculator on the sheet page, and check Ship leftovers if you want the extra pieces too. See how custom cuts work.
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.
