  • Specifications are as follows:

Class A
One-Piece Appearance — Most Costly

Class B

Minimal Touch-Up — Less Costly

Materials will not be pre-polished prior to fabrication. Welders will TIG weld with filler so no under-cut will be present. Welds will not be ground smooth.

No Touch-Up — Least Costly
