GULFTEX Fence & Gate — 12 Steel Ranges

IN THE HOUSTON WAREHOUSE

Two sizes are on our floor right now

These two are not catalogue pictures. They are our own pallets at 9500 W Sam Houston Pkwy S, photographed where they stand. Come and look at them, or collect them the same day. The rest of the twelve ranges is quoted to order.

Stacks of 6 by 8 foot 14 gauge steel fence panels in the Cube-Age Houston warehouse — 6 ft × 8 ft panel · 14 gauge

Pickets 1 in · Rails 1-1/2 in · spear top

The heavier of the two. Thicker wall on both the rails and the pickets, which is what you want on a run that takes wind or a gate that gets used every day.

Bubble-wrapped pallet of 6 by 8 foot 15 gauge steel fence panels in the Cube-Age Houston warehouse — 6 ft × 8 ft panel · 15 gauge

Pickets 3/4 in · Rails 1 in · spear top

The lighter build, and the one most residential jobs are priced on. Same finish and same spear top, less steel in the section.

WHY IT LASTS

Fifteen to twenty years before the steel sees rust

That is the supplier’s figure for inland Texas exposure, and it rests on one extra step most powder-coated fence skips: a cathodic e-coat under the colour. Every powder-coated fence looks the same on day one. What separates them is what sits under the paint, and whether the coating reached the corners a spray gun cannot.

The substrate

ASTM A653 G60 pre-galvanized steel — about 180 g/m² of zinc spread across both faces. The zinc is the part that keeps working after the paint is scratched.

The e-coat

After a nano-ceramic pre-treatment the panel is dipped and charged, so the film is deposited electrically rather than sprayed. It reaches inside corners, weld joints and the back faces of pickets, which is where a sprayed-only fence starts rusting first.

The topcoat

Outdoor-grade polyester powder with UV inhibitors, cured on top of the e-coat. Tested to ASTM B117 salt spray at 1,200 hours or more with no red rust.

WORTH KNOWING BEFORE YOU SPECIFY

G60 is a comparatively thin zinc layer, and salt eats it faster. The brand rates the standard build at 15 to 20 years inland and 6 to 10 years in high-salt coastal exposure, and offers a G90 substrate — 275 g/m² — that takes the coastal figure to 12 to 16 years. If the job is close to the water, ask for G90 at quote stage rather than after.

WITH THE E-COAT — THIS LINE

15–20 years

inland Texas · no rust on the base steel

Dropping to 10–15 years in an urban or light industrial setting and 6–10 within reach of salt air. Salt spray to ASTM B117 at 1,200 hours or more with no red rust.

GALVANIZED OR POWDER ALONE

roughly 7–11 years

same exposure · derived, not measured

The supplier rates the three-layer system at 1.8 to 2.3 times the protection of single galvanizing or powder coat on its own. Divide the inland figure by that and you get this band — which is the gap you are actually buying, and the point at which a fence starts needing paint.

Service life, salt-spray result and the 1.8–2.3× multiplier are all GULFTEX’s own published figures. The 7–11 year band is arithmetic on that multiplier, not an independent test, and no figure here is a written warranty — ask us for one before you specify.

WHAT IT LOOKS LIKE WHEN THAT LAYER IS NOT THERE

New panels. Never installed. Already rusting.

These are powder-coat-only panels from other brands that we keep on hand for comparison. They have never been in the ground — they are stacked indoors in Houston, still in their cardboard. The rust is at the picket joints and the cut ends, which is precisely where a sprayed coating stops and a dipped one does not. We are not naming the maker; the point is the mechanism, and it is the same on any panel finished this way.

Rust bleeding from the joints where pickets pass through the rail on a powder-coated steel fence panel — Where the picket meets the rail

Rust bleeding out of every joint. The gun never reached inside the punched hole, so there was nothing on that surface to start with.

A ring of rust around the cut end of a powder-coated steel fence rail — The cut end of a rail

A ring of rust right around the cut. Every panel has these, and a sprayed finish has no way of covering them.

Looking down the inside of a fence rail: bare grey steel with no coating — Looking down the inside

Bare mill surface the whole way down. A dipped panel carries film on this face too; a sprayed one never does.

A stack of new powder-coated fence panels still in cardboard, showing rust along the rails — Still on the stack

Not a weathered fence. New panels, indoors, in their packaging — and the rails are already going at the joints.

WHAT IS IN THE BOOK

Twelve ranges, one spec sheet

Most ranges come as two-rail and three-rail panels with matching walk gates at 3 to 6 ft and drive gates at 12 to 18 ft. Panel heights run 4 to 8 ft, custom heights on request. Posts and hardware are quoted separately from the panels.

01 · ORNAMENTAL

Pressed Spear

The classic spear-top picket, in two-rail and three-rail panels.

02 · ORNAMENTAL

Pressed Spear / Flat Bottom

Spear top, clean bottom rail. Sits better on level ground.

03 · ORNAMENTAL

Flat Top

Flush picket tops — the quiet option for front yards and pools.

04 · ORNAMENTAL

Flat Top / Flat Bottom

Flat at both ends, so the panel reads as a frame rather than a fence.

05 · ORNAMENTAL

Curved Top

Bowed picket tops. Usually specified on commercial perimeters.

Horizontal slat steel fence in front of a modern house

06 · MODERN

Horizontal & Vertical Slats

Wide slats, spacing from flush to 1-3/16 in. Custom sizes and colors.

07 · MODERN

3D Vertical Blade

Angled blades, so the run reads open head-on and closed from the street.

Steel balustrade railing on a raised deck

08 · RAILING

Railing and Balustrade

Deck and stair railing in the same finish as the fence it meets.

Steel posts, post caps and finials from the GULFTEX accessory range

09 · HARDWARE

Hardware & Accessories

Posts, caps, finials, brackets, scrolls and gate fittings.

10 · OTHER MATERIALS

Vinyl Fence

Privacy and picket profiles in white, chocolate, army green and black.

INSIDE THE PLANT

Three clips from the line

Short videos from the brand’s own plant — the cutting bed, the dip tanks and the powder booth. They are the three stages that decide whether a panel is straight and whether the coating holds.

Cutting the rail

Rail stock is cut and slotted on a laser bed before the pickets go in, which is what keeps the picket spacing even down a long run.

0:32 · NO SOUND NEEDED

Into the tanks

Welded panels lowered down the pre-treatment and e-coat line. This is the stage a spray-only shop does not have.

0:23 · NO SOUND NEEDED

The powder booth

Racked panels passing the electrostatic guns, on their way to the curing oven.

0:11 · NO SOUND NEEDED

Twelve-stage production flow from raw material to shipment

We mention the powder brand because it is one of the few things a buyer can check without a lab. The pre-treatment chemistry on this line is Henkel Bonderite; the topcoat powder is PPG. Neither of those is a certification, but a plant buying branded chemistry is at least not buying the cheapest drum on the dock.
