HDA 2-Rail PVC Farm Fence: Two-Rail Vinyl Sections for Pasture, Paddock and Property Lines

As an HDA 2-rail pvc farm fence manufacturer, Deqing Huazhijie Railing & Fencing Co., Ltd. produces two-rail vinyl fence sections at our plant in Deqing, Huzhou, near Shanghai. The HDA system is a low, open barrier: two ribbed rails set into pre-routed posts with no pickets between them, which suits pasture perimeters, horse paddocks, ranch boundaries, pet runs and residential property lines where visibility and airflow matter more than screening.

We extrude the profiles, cut to length, drill and notch the rails, route the posts and pack the sections in our own production line. Matching gates are built to the same profile and colour, so a completed run closes without mixing components from different systems.

What Ships in an HDA Section

Every HDA section is a kit of pre-machined parts rather than loose profile. The table below reflects the standard configuration and the variations we produce on request.

Reading the Specifications

Height and width

36" is the standard section height and 96" the standard section width. Both are working dimensions rather than fixed ones. We cut sections to the run length you specify, and taller or shorter configurations are produced where a project calls for a different rail line relative to the animals or the boundary being held.

Posts and routing

Posts arrive pre-routed, and the routing pattern is set by the position each post occupies in the run. Line posts carry rails straight through, end posts close a run, corner posts turn it, and 3-way posts form a T-junction. Blank posts are supplied where the installer prefers to route on site. Post length options include 60" and other lengths, so the above-grade height and the buried portion can be balanced against local ground conditions and frost depth.

Ribbed rails

Each section carries two ribbed rails at 1-1/2" x 5-1/2" x 94", supplied pre-notched in two pieces. The rib stiffens the rail across its span, and the notch locates the rail inside the post rout. Together with the heavier-wall post and rail configuration, that geometry contributes to greater resistance to pull-out and a straighter rail line under animal contact.

Configuration Options and Custom Sections

HDA is a configurable system rather than a single catalogue item. The variables that change most often on farm and ranch projects are the routing mix, the post size, the section height and the colour.

• Routing mix — a run is quoted as a count of line, end, corner, 3-way and blank posts, so the delivered kit matches the layout drawing.
• Post size — 4" x 4" for standard runs, 5" x 5" where a heavier post is wanted for longer spans or higher wind exposure.
• Height and width — standard 36" x 96" sections, with other heights and widths produced to the project dimension.
• Colour — White, Tan, Grey and Cream, with OEM colour requirements reviewed during enquiry.
• Gates — matching gates in the same profile and colour, sized to the opening.

Where a project needs a different rail count or a different visual rhythm, the three-rail HDB 3-rail PVC horse fence and the four-rail HDC 4-rail PVC ranch fence use the same post and cap family, so a property can combine rail counts without changing the post system.

Material Formulation and Weather Performance

The profiles are extruded from 100% virgin PVC with no recycled content and no lead. UV protection comes from titanium dioxide dosed at 10 parts per 100, supported by US or German brand pigments, and all raw materials are traceable through production. The formulation is built to resist chalking, cracking, chipping, peeling and rot, and it does not support termites.

Working temperature range is -40°C to 70°C, which covers the seasonal swing on Canadian, northern US, European and Australasian installations. Because the material is elastic and impact resistant, the rail line recovers from livestock pressure instead of splintering the way timber does. Huazhijie vinyl fence carries a 30-year limited warranty.

Installation, Gates and Site Interfaces

HDA installs much like a wood fence, but with the machining already done. Posts come routed from the factory, rails are pre-notched and components are precut for standard installation, so site work is assembly rather than fabrication.

1. Set the posts to the layout, treating vinyl posts the same way as wood posts — where local practice is to cement wood posts, cement the vinyl posts as well.
2. Insert the rails into the routed post openings, keeping the rail line level across the run.
3. Fit the post caps after the fence is installed.
4. Hang the matching gate and check the swing against the opening.

We provide video installation guidance with the order, and the same routing logic applies to the HBG plastic rail fence where a rail-style boundary is needed in a different setting.

Quality Control and Acceptance Evidence

Production runs on our extrusion lines, followed by cutting, hole drilling, notching, packing and storage. An independent quality-control group inspects each extruder's output every hour and carries out additional random checks, so wall thickness, colour consistency and machining accuracy are monitored through the shift rather than at final packing only.

• Product documentation: SGS, CE and ISO 9001 for the fence range
• Company certifications: CE, ROHS and UL94
• Quality system references: ASTM and TUV Global Manufacturer Certificate
• Traceability: raw material batches recorded from resin, TiO2 and pigment intake through extrusion

Certificates and test documentation are issued with the order pack so the material can be presented to inspectors, distributors or project owners without a separate request cycle.

Information We Use to Configure Your Solution

A firm quotation for an HDA run is prepared from the layout, not from a per-metre estimate. The following inputs let us fix the section count, routing mix, gate sizes and packing plan in one pass.

We also take OEM and ODM orders and develop new fence profiles and styles from a customer's drawing or sample. Our engineering team reviews the requirement, proposes the profile and machining, and produces samples before a production run is scheduled.

Maintenance, Spare Parts and Serviceability

Routine care is a garden hose rinse. Stubborn marks come off with a mild abrasive cleaner of the type used on fibreglass tubs, and graffiti generally lifts with ordinary detergent, a pressure washer, or in difficult cases a paint thinner. The surface is never painted or stained, so there is no recoat cycle to schedule.

Because the system is modular, a damaged rail or post is replaced individually: the cap lifts off, the rail slides out of the rout and a new piece goes in. We keep rails, posts, caps and gate hardware available as separate line items so a distributor or maintenance team can hold spares against the installed configuration.

Frequently Asked Questions

What are the standard dimensions of the HDA 2-rail PVC farm fence?

Standard section height is 36" and standard width is 96". Posts are 4" x 4" or 5" x 5", pre-routed, and each section carries two ribbed rails at 1-1/2" x 5-1/2" x 94", supplied pre-notched in two pieces. A flat cap finishes each post.

Can the fence be produced in other heights and widths?

Yes. Different heights and different widths are available, and sections are cut to the run length on the order. Post lengths other than the standard also allow the above-grade height and buried portion to be set for the site.

Is a two-rail fence suitable for horses and other livestock?

The HDA section is designed for farm, horse, ranch and pet use. The open two-rail layout keeps animals visible across the boundary, and the elastic, high-impact PVC formulation flexes under contact rather than splintering. For higher containment or a denser rail line, the three-rail and four-rail versions in the same post family are available.

Which colours and post caps can I order?

White, Tan, Grey and Cream are the standard colours. Four different post cap profiles are available across the range, and the flat cap is the standard finish for the HDA section.

Do you supply matching gates and how is the fence packed?

Matching gates are available in the same profile and colour, sized to the opening. Each section occupies 0.05 CBM, and the loading quantity is confirmed against the final order mix and destination port.

What warranty and certification apply?

Huazhijie vinyl fence carries a 30-year limited warranty. The fence range is documented with SGS, CE and ISO 9001, and the company holds CE, ROHS and UL94 certificates alongside ASTM and TUV Global Manufacturer Certificate references.
