Galvanized, With a Clear Coat on Top.
Heidtman adds clear coat to galvanized tube. Every galvanized size leaves our mill clear coated as standard, or with a conductive clear coat that meets UL 2703 for solar racking, cured in line by ultraviolet light.
How Clear Coat WorksHelps Against White Rust
A sealed surface keeps more trapped water off the zinc, so tube stays bright longer in the bundle and on the truck.
Bends and Forms
The coat stays flexible after months outdoors and passes a bend test around a 3/8 inch mandrel without cracking.
Clear or Conductive
Conductive clear coat protects the same way, and parts can still be bonded and grounded through it.
From Coil to Tube Without Leaving the Family.
Heidtman Steel buys the coil, sister plants pickle or galvanize it, and in Erie we slit it, form it, weld it and cut it. One company answers for the steel from mill to bundle.
See How Tube Is MadeA Tube Mill Inside a Steel Company.
We are part of Heidtman Steel, so our coil is bought and pickled or galvanized by our own family before it reaches the mill.
ISO 9001 and IATF 16949
The Erie plant is registered to both; IATF 16949 is the automotive quality standard.
Traced to the Heat
Every bundle tag carries the heat number, and mill test reports go with every shipment.
Clear Coat as Standard
Galvanized tube leaves the mill clear coated, with conductive clear coat to UL 2703 for solar.

Heidtman can legally import your material, make it into tube and export it.
