Ornamental iron Gate Designs
Over the years, we have built steel gates using conventional steel shapes such
as tubing, solid bar stock and channels. Experience has shown that utilizing the
rigid strength of steel tube for the frame, or at least for the hinge-side
upright and bottom horizontal members, and using solid bar stock for the
intermediates and perhaps the sweeping tops, so common in iron gates, makes for
the best overall job. The tubing provides the stiffness to overcome whip, which
is common in steel bar framework. Solid bar intermediates (pickets) can be
formed, forged or twisted into almost any shape. AutoGate Systems have
available, some fine architectural forge work that is bought in component form,
and then produce an elegant iron gate at a reasonable cost. Steel is probably
the most versatile and surely the strongest material to work with, either as the
sub-structure of wood or aluminum, or on it’s own. We prefer a natural iron
finish on ornamental gates, which requires a three - step process:
- The completed panel is sandblasted to remove all mill scale,
weld spatter, etc. - The panel is acid washed, then rinsed, several
times.
- Acrylic clear-coat is applied, several coats in thickness, to preserve
the finish. Of course, iron gates can be painted as well, but the proper
job requires sandblasting also. It should be noted that all steelwork discussed
here, whether structural or ornamental (painted) is epoxy coated after
fabrication using the following process: - Sandblasting or chemical
cleaning/etching - Applied epoxy: DeVoe Bar-rust 235 primer Marine
Coating - Applied epoxy: DeVoe Devran 229 top coat Marine
Coating
This product is expensive, but has proven itself in saltwater
marine use on commercial steel ships, buoys, Mil spec. Etc. All steelwork is
coated in the shop, after fabrication. In the event of any on-site welding,
drilling or repairs, the process can be mixed in the shop and applied in the
field.
Conventional red metal primer used by most metal shops is grossly
inadequate for exposed steelwork. In modern paint formulas, the only metal found
in red metal primer is the container itself.
