HAE1 traditional dog ear picket

Deqing Huazhijie Railing & Fencing Co., Ltd. has produced PVC fence profiles and complete fence systems from Huzhou, near Shanghai, since 2003. As a HAE1 traditional dog ear picket manufacturer, we extrude, cut, drill, notch and pack every component of the section ourselves, then ship it as a kit that installs without field fabrication. The range serves residential front yards, estate boundaries, park and garden perimeters, and commercial picket runs where a classic American picket line is wanted in vinyl rather than wood.

The HAE1 Section: What Ships in the Kit

The HAE1 is a traditional dog ear picket system built around a 7/8" x 3" picket with the rounded dog ear top profile. A standard section is 48" high and 96" wide, carrying 15 pickets at standard spacing between a pre-notched top rail and a pre-notched bottom rail. Posts are routed at our factory, so the installer receives parts that already accept rails and pickets in the correct orientation.

• Panel kit includes all rails and pickets for the section.
• Aluminum insert runs inside the bottom rail for commercial-grade strength.
• Posts are supplied pre-routed as Line, End, Corner, 3-way or blank.
• Matching gates are available so the picket line reads continuously across an opening.
• Post caps are ordered with the run: New England, Flat or Gothic.

Section Anatomy and Specification Meaning

Each dimension in the table below drives something on site — picket count drives the visual rhythm, rail length drives post spacing, and section volume drives container loading. We confirm all of them against your layout before the extrusion schedule is released.

Picket Profile, Spacing and Visual Character

The dog ear top is the detail that separates this fence from a flat-top or spade picket line. The rounded shoulder softens the silhouette against a lawn or planting bed while keeping the picket face flat and easy to clean. Fifteen pickets across a 96" section gives an even rhythm that reads as a traditional picket fence from the street and from inside the property.

Spacing is a design decision as much as a structural one. Wider spacing opens sightlines and reduces material per metre; tighter spacing increases privacy and wind loading on the posts. We set the picket count and spacing together with the post routing so the section lands on the post centres you have planned. Where a different visual weight is needed, the HAF 1"x1" small picket fence uses a slimmer picket for a lighter, more decorative line.

Heights, Widths and Layout Configurations

Standard production is 48" high by 96" wide, and we build other heights and widths on the same extrusion tooling. Height changes are usually driven by local boundary rules or by the level of separation the site needs; width changes are usually driven by the distance between fixed points such as a wall, a driveway edge or a gate post.

• Line posts carry sections straight through a run.
• End posts terminate a run and take a single rail set.
• Corner posts accept rails on two adjacent faces.
• 3-way posts accept rails on three faces at a T-junction.
• Blank posts are unrouted for gate frames and site-specific details.

Where a shorter run is required, the HAD2 white vinyl fence 4'Hx8'W shares the same 4 ft height and 8 ft width module, which keeps a mixed project visually consistent.

Material Formulation and Weather Performance

The HAE1 is extruded from 100% virgin PVC and is not coated, so the colour runs through the profile rather than sitting on the surface. Virgin vinyl does not absorb water, which removes the rot mechanism that shortens the life of a timber picket fence. Our formulation uses DuPont TiO2 at 10 parts per 100 as a UV inhibitor, together with US or German brand pigments and domestically sourced PVC resin, all traceable back to the batch.

The compound is lead-free, and the fence is rated V-0 for fire performance. Service temperature range is -40°C to 70°C, which covers Canadian and northern US winters as well as Australian and Middle Eastern summer exposure. Products carry a 30-year limited warranty.

Installation Sequence and Site Interfaces

Installation follows the same logic as a timber picket fence, with the fabrication already done. Posts are set first, then rails are inserted into the routed post openings, then pickets drop into the notched rails and the caps go on last. Because the rails arrive pre-notched and the posts arrive pre-routed, the on-site work is alignment and fixing rather than cutting and drilling.

1. Set out post centres from the section width and confirm the gate opening.
2. Excavate and set posts; we recommend treating vinyl posts the same way as wood posts, including cementing where that is local practice.
3. Check line, level and post height before backfilling.
4. Insert the top and bottom rails into the routed post openings.
5. Feed the pickets into the notched rails and seat them evenly.
6. Fit post caps and hang the matching gate on its blank posts.

The aluminum insert in the bottom rail stiffens the section against sag over long spans and is the detail we specify when a run is exposed to wind or is used in commercial and multi-unit work.

Quality Control and Acceptance Evidence

Production runs through extrusion, cutting, hole drilling, notching, packing and storage under one roof, which keeps the section components matched to each other. An independent quality-control group inspects each extruder's output every hour and carries out additional random checks across the shift.

• Raw materials are traceable to supplier and batch.
• Certification held includes SGS, CE, ISO 9001 and TUV Global Manufacturer Certificate.
• Fire performance is documented at V-0.
• Finished sections are counted and packed by section, with posts, caps and gates listed separately for site reconciliation.

OEM, ODM and Matching Accessories

We take OEM and ODM work on the HAE1 platform: custom heights, custom widths, picket spacing changes, colour matching and private-label packaging. New fence profiles and styles can be developed from a drawing or a sample. Accessories are quoted with the fence so the run is complete on arrival — the HAG crown cap for picket fence is one of the cap options used to finish post tops, alongside the New England, Flat and Gothic caps.

Colours are held in White, Tan, Grey and Cream as standard. A 40HQ order is typically delivered in 7-10 days from confirmation, and we will confirm the schedule against the actual quantity and colour mix on your order.

Information We Use to Configure Your Solution

To turn an enquiry into a firm configuration and quotation, we work from the following project inputs. Send what you have; we will confirm the rest with you rather than assume it.

• Total run length and the number of separate fence lines.
• Required height and width, or the fixed points the fence must fit between.
• Post centres and whether posts will be set in concrete or in another foundation type.
• Number, position and leaf type of gates.
• Colour, cap style and any picket spacing requirement.
• Post size preference: 4" x 4" or 5" x 5".
• Site conditions: wind exposure, ground slope, soil type and frost depth.
• Destination port, container type and required documentation.
• Whether the order is a catalogue selection or an OEM/ODM development.

Frequently Asked Questions

What is included in a standard HAE1 section kit?

One section contains 15 pickets at 7/8" x 3" x 39", a pre-notched top rail and a pre-notched bottom rail at 2" x 3-1/2" x 94", and an aluminum insert in the bottom rail. Posts, post caps and gates are quoted separately because their quantity depends on the run layout.

Can the HAE1 be produced in heights and widths other than 48" x 96"?

Yes. Standard production is 48" high by 96" wide, and different heights and widths are available on the same profile family. Give us the run length and the fixed points, and we will set the section module and post centres to suit.

How are the posts supplied?

Posts are 4" x 4" or 5" x 5" and are pre-routed at our factory as Line, End, Corner, 3-way or blank, with a 72" length option. Blank posts are used for gate frames and for details that are cut on site.

Does the fence need painting, sealing or annual treatment?

No. The colour is in the profile, not on it. Normal cleaning is a rinse with a garden hose; stubborn marks come off with a mild abrasive cleaner of the type used on fibreglass baths, and most graffiti can be removed with ordinary detergent and water.

What colours and cap styles are available?

Standard colours are White, Tan, Grey and Cream. Post caps are supplied as New England, Flat or Gothic, and crown caps are available where a heavier post top is wanted.

Can you supply a complete fence with gates for a project?

Yes. Matching gates are made for the HAE1 picket line, and we quote the full bill of materials — sections, posts, caps, gates and hardware — so the site receives one coordinated delivery rather than parts from several sources.
