Galvanized Steel Coil Supplier
A late coil or an off-spec stack of cut sheet can idle a stamping line and push a fab shop behind schedule. Curtis Steel Company works as a galvanized steel coil supplier with enough inventory on hand that you can order from our floor instead of waiting on a mill's schedule.
We stock galvanized coil and galvanized steel sheet in Houston, Dallas-Fort Worth, and Harlingen, and our own truck fleet handles local delivery.
Galvanized Steel Sheet and Coil Stocked Deep and Made to ASTM A653
Galvanized steel is carbon steel with a zinc layer on both sides. The zinc corrodes first, so scratches, drill holes, and cut edges stay protected from rust. We carry hot-dipped galvanized steel that meets ASTM A653 and electro-galvanized steel that meets ASTM A879, in G30, G40, G60, and G90 coating weights.
Buyers in the construction, automotive, agricultural, telecommunications, and infrastructure industries rely on that coating to hold off rust and keep maintenance costs down long after installation.
Galvanized Steel Coil in the Widths and Gauges Your Line Runs On
Stamping presses, roll formers, and duct lines need coil that feeds clean and holds gauge from the first wrap to the last.
We stock galvanized steel coil in three standard widths and slit it in-house when your line calls for something narrower.
- Specification: ASTM A653, Grade CS-B, Min Spangle, CT-Dry treatment
- Coil widths: 36", 48", and 60"
- G90 gauges: 14 GA through 26 GA in all three widths; 10 GA through 13 GA in 48" and 60"
- G60: 28 GA in 36", 48", and 60"
- G30: 30 GA in 36" and 48"
- Finishes: Min Spangle standard; Regular Spangle available in 26 and 28 GA
- Slit coil: 5.394" and 5.5" widths for spiral pipe, plus 1" hanger strap

Material Types
Each grade of galvanized steel sheet and coil behaves differently in a press brake or a draw die. Matching the grade to your part cuts down on cracked parts and rework. We stock:
- Commercial Steel (CS Types A, B, and C) for general bending and forming
- Forming Steel (FS Types A and B) for parts that need more formability than CS
- Deep Drawing Steel (DDS Types A and C) for drawn components
- Extra Deep Drawing Steel (EDDS) for the most severe draws
- Structural Steel (SS) in Grades 33, 37, 40, 50, and 80, numbered by minimum yield strength in ksi
- High Strength Low Alloy Steel (HSLAS) for added strength at a lighter gauge
Tell our sales team what you're making, and they'll recommend the grade that fits.
The Industries That Rely on a Trustworthy Galvanized Steel Supplier
More than 1,500 customers count on Curtis Steel as their galvanized steel supplier. Contractors use our coil and sheet to frame commercial and residential buildings, and metal building fabricators turn it into purlins, wall panels, and trim.
Farms and ranches build agricultural fencing and barns with it, and HVAC shops feed it through duct lines for ductwork and ventilation. Automotive manufacturers form it into bodies and frames.
Utility and telecom companies use it for equipment cabinets, and manufacturers build industrial shelving and storage systems from it.
The Galvanized Steel Supplier Texas Shops Have Trusted Since 1976
Curtis Steel started as a small coil processor in Houston and has stayed privately owned ever since. We still do our processing in-house.
Our Braner 60" slitting line, Red Bud 72" multi-cut blanking line, and Cincinnati leveling and shearing lines handle slitting, cut-to-length, shearing, multi-blanking, and leveling on-site, so your galvanized steel coil or sheet arrives at the width and length your job calls for.
Running our own equipment lets us set our production schedule instead of waiting in line at an outside processor.
Large-volume buyers outside Texas can order through our National Steel program, which works through processing hubs in Chicago and St. Louis and keeps 50,000 to 70,000 tons of steel in stock.
