We're not just a panel shop. Mad Steel sells and delivers every material you need — panels, tubing, doors, windows, screws, trim — and we build the structure too if you want. One call. One company. Done right.
Most customers hear back within the hour — from the owner.
From standard roofing to architectural looks — we carry the panel for your job. All available by the sheet or by the project load with delivery to your site.
The workhorse of the steel panel world. High-rib structural panel used for roofing and siding on carports, garages, barns, and commercial buildings. Excellent water runoff and strength.
A low-rib corrugated panel with a clean, traditional look. Popular for residential roofing, patio covers, and agricultural buildings where a flatter profile is preferred.
A wider-rib structural panel with a 7.2" rib spacing. Strong, fast to install, and used widely on commercial and industrial roofing and wall applications.
A deep-corrugated panel built for maximum structural strength and long spans. Ideal for wide-span buildings, agricultural structures, and industrial applications.
A standing-seam style panel with a U-shaped profile. Clean, modern appearance with excellent weather resistance. Popular for walls and roofing where aesthetics matter.
Steel panels that replicate the classic look of Spanish clay tile — without the weight, maintenance, or cost. Perfect for homes where curb appeal matters.
Translucent clear panels in the L-5 profile. Mix with standard L-5 steel panels to bring natural daylight into carports, barns, workshops, and covered patios without cutting holes in your roof.
Translucent clear panels in the PBR profile. Installs alongside standard PBR steel panels for a seamless look. Ideal for garages, ag buildings, and any structure where you want light without electricity.
32 colors available. Solid, textured, and metallic finishes. Not sure which fits your project? Ask the owner — we'll help you pick.
From light residential framing to heavy-duty structural builds — we stock square steel tubing across the full range. Contractors and DIYers, we have what you need, and we deliver to your site.

Call us and you get the person who built the business. Not a rep reading off a script. Straight answers from someone who knows steel.
Most suppliers only sell you steel and send you on your way. We supply every material AND build the structure. One call handles everything.
We deliver panels, tubing, doors, and accessories directly to your job site so you're not making multiple trips to the yard.
8 panel profiles (including clear skylights), 9 tubing sizes across multiple gauges, Cee/Zee/C channel, roll-up doors, walk-in doors, windows, screws, trim, and insulation. If it's steel, we have it.
Reach out and most customers have a real quote from the owner the same day — not 3 days later from a sales rep.
