A 500 Tube / A 513 Tube
A 500, A 513, A 787, HR, HSS, CR, Galvanized, Powder-Coated
Produced in North America.

We are mill producers of structural and mechanical ERW tubing. 
With production facilities strategically located in North America, we are able to serve your manufacturing material requirements quickly and efficiently.

Our A513 and A500 dimensional capabilities range from .500" to 6.250" round plus squares .500" x .500" through 5" x 5" and rectangles as large as 8" x 2".
Our wall thickness range is .035" through .250" nominal wall. We ship LTL and in full truckload quantities.
This is produced with C1018 to C1022 hot rolled steel and lightly oiled to inhibit oxidation. The yield, tensile and elongation vary for Grades A, B, C or D. Mill lengths are available up to 45 feet. The product shown below is light wall with a punch-cut end. Saw-cut and de-dimpled ends are also produced.

We offer post production services.

These services include de-dimpling, de-burring, secondary cut to length, on site chemistry verification, tensile tests and boxing.
A 513 mechanical tubing is produced from .500" to 6.625" diameter. Wall thick ranges from .032" to .300". Cold rolled hot rolled and P&O. Most of our dimensions can be produced to A513 specifications. Contact us for an A500 dimensional chart. Mill minimum order quantities start at 5,000 feet.

We produce galvanized and galvannealed tubing, remetalized and cut to length. Inside diameter flash control is available.. Galvanized is produced from G-40 to G-235. We offer secondary cutting for tighter tolerances and lengths under mill minimum requirements.  
 Galvanized with in-line acrylic clear-coating shown above.
