HAC1 picket fence 4'Hx8'W

Deqing Huazhijie Railing & Fencing Co.,Ltd. has manufactured PVC fencing in Deqing, Huzhou, near Shanghai, since 2003. The picket fence 4'Hx8'W manufacturer line is one of our core picket profiles: a pre-routed panel system extruded from 100% virgin PVC and supplied as sections, posts and matching gates that assemble into a finished fence line without field drilling.

The panel suits garden, home, farm, villa, warehouse, country yard and balcony boundaries where a clean picket line, low maintenance and long service life matter more than full visual screening. Every component is extruded, cut, drilled and notched on our own production line before packing.

What Ships in a Standard HAC1 Section

The 4'H x 8'W designation describes a nominal 48 in high by 96 in wide panel. Rails are cut at 94 in so they seat into the routed post walls, and pickets are cut at 39 in to sit between the two rails.

Reading the Specification Correctly

Three numbers drive the whole assembly: picket spacing, rail length and post routing. Because the rails are notched and the posts are routed before shipment, finished panel height and picket alignment are set by tooling rather than by the installer's tape measure.

• Picket 7/8 in x 3 in x 39 in, 15 pieces per section at standard spacing — the picket length is what fixes the visible field between the two rails.
• Rails 2 in x 3-1/2 in x 94 in, pre-notched, one top and one bottom — the 94 in cut leaves the rail ends inside the routed post walls.
• Aluminum insert in the bottom rail — adds stiffness across the 8 ft span and is the reason the panel holds up in commercial and farm installations.
• Posts 4 in x 4 in or 5 in x 5 in at 72 in, pre-routed as line, end, corner, 3-way or blank. A 72 in post gives roughly 48 in above grade plus setting depth.
• Post caps in New England, flat or Gothic — fitted after the fence is assembled, not before.

Where the HAC1 Fits on a Project

The HAC1 is an open picket design. It defines a boundary and controls movement without blocking sight lines or airflow, which is what most front-yard, farm and yard-demarcation projects actually need.

• Residential front and side boundaries — a 4 ft picket line reads as a garden fence rather than a barrier.
• Farm and rural property lines — the reinforced bottom rail and high impact resistance suit long runs exposed to wind and livestock contact.
• Villa and estate perimeter — colour-matched sections, posts and gates keep the line consistent around a full boundary.
• Warehouse and commercial yard demarcation — a low-maintenance way to separate pedestrian and vehicle zones.
• Balcony, terrace and temporary layouts — panels can be dismantled and re-used because the joints are mechanical, not glued.

Where a solid screen is required, our privacy and semi-private panel ranges cover that requirement. Within the PVC picket fence range, the picket line continues with profiles such as the HAC2 7/8"x3" plastic picket for projects that want a different picket face.

Configuration Options and Ordering Logic

Ordering follows one build rule: section + post + gate = complete fence. Everything else is a choice inside those three groups.

• Section: height, width, colour and picket spacing.
• Post: 4 in x 4 in or 5 in x 5 in, routing type per position, cap style.
• Gate: a matching gate keeps the same picket line, colour and height as the panel — see our PVC fence gate range for leaf and hardware options.

Material and Weather Performance

The HAC1 is extruded from 100% virgin PVC with no recycled content and no lead, and it is not coated — the colour runs through the profile rather than sitting on the surface. The formulation carries UV stabilisers and impact modifiers, with DuPont TiO2 dosed at 10 parts per 100 to resist chalking under sustained sun exposure.

• Moisture resistant: will not rot or warp the way a wood picket fence does.
• Fire performance: V-0 rated.
• Temperature range: from -40°C to 70°C.
• Mechanical behaviour: high impact resistance with enough elasticity to absorb knocks without cracking.
• Certification evidence: SGS, CE and ISO9001 on the product; CE, ROHS and UL94 held at company level.

Manufacturing and Quality Control

Production runs through extrusion, cutting, drilling, notching, packing and storage. Extrusion is where wall thickness, colour consistency and impact performance are set, so it carries the tightest control on the line.

An independent quality-control group inspects each extruder's output every hour and carries out additional random checks across the shift. Raw materials — PVC resin, TiO2 and pigments — are traceable back to supplier batches, which is what allows a colour or profile question to be answered against a specific production run.

Installation and Site Interfaces

Posts arrive routed, rails arrive notched and pickets arrive cut to length, so installation follows the same sequence as a wood fence with far less cutting on site.

1. Set posts to line and grade, using the correct routing type at each position.
2. Insert the top and bottom rails into the routed post openings.
3. Insert pickets into the notched rails at the designed spacing.
4. Fit post caps after the fence is assembled.
5. Hang gates on the gate posts and check swing and latch alignment.

Set vinyl posts the way you would set wood posts in the same location. Wind exposure, soil type and frost depth determine setting depth and whether 4 in x 4 in or 5 in x 5 in posts are appropriate; the aluminum insert in the bottom rail adds stiffness across the 8 ft span.

Maintenance, Spare Parts and Serviceability

Routine care is a garden hose rinse. Stubborn marks respond to a mild abrasive cleaner, and graffiti generally lifts with ordinary detergent, a pressure washer or, in difficult cases, paint thinner or dry-cleaning fluid. Spots that resist all of these can be worked back with 400 grit sandpaper.

• Individual pickets, rails, posts and caps are replaceable without dismantling the full run.
• No painting, staining or sealing at any point in the service life.
• No termites, no rot and no harmful chemicals in the profile.
• The HAC1 carries a 30-year limited warranty.

Information We Use to Configure Your Solution

A quotation is only accurate when it is built on the actual fence line. We work from the following inputs to produce a section, post and gate schedule.

• Total linear run, plus a plan or sketch showing corners, ends and T-junctions.
• Gate positions, leaf widths and hinge side.
• Required panel height and width, if not the standard 48 in x 96 in.
• Colour and post cap style.
• Picket spacing preference.
• Post size and routing type per position.
• Site conditions: wind exposure, soil, frost depth and slope.
• Container or loading target, and delivery destination.
• OEM or ODM requirements covering profile, packaging, branding and documentation.

With those inputs we return a component schedule, a loading estimate based on 0.08 CBM per section, and a delivery plan. Standard 40HQ orders run about 7-10 days, and the HS code for the product is 3925900000.

Frequently Asked Questions

What is included in one HAC1 picket fence 4'Hx8'W section?

One top rail and one bottom rail at 2 in x 3-1/2 in x 94 in, both pre-notched; fifteen pickets at 7/8 in x 3 in x 39 in at standard spacing; and an aluminum insert in the bottom rail. Posts, post caps and gates are ordered separately so the post type matches each position on the line.

Can the HAC1 be supplied in heights or widths other than 4 ft x 8 ft?

Yes. 48 in x 96 in is the standard panel, and different heights and widths are available. Picket spacing, post size and cap style are also configurable, and we develop new fence profiles and styles for OEM and ODM orders.

Is the HAC1 suitable for privacy screening?

No. It is an open picket design that marks a boundary and controls access while keeping sight lines and airflow open. For solid screening, our privacy and semi-private panel ranges are the correct starting point.

Do the posts need to be concreted?

Treat vinyl posts the same as wood posts in the same location. If local practice is to concrete wood posts, concrete the vinyl posts to the same depth. Wind load, soil and frost depth determine the final setting depth and whether 4 in x 4 in or 5 in x 5 in posts are the right choice.

What colours, caps and gates are available?

White, tan, grey and cream, with New England, flat or Gothic post caps. Matching gates are available so the gate follows the same picket line, colour and height as the panel.

What warranty and delivery terms apply?

The HAC1 carries a 30-year limited warranty. Standard 40HQ orders ship in about 7-10 days, and the HS code for the product is 3925900000.
