What a plastic barrier fence manufacturer supplies
A plastic barrier fence manufacturer makes the high-visibility construction safety fence that keeps the public out of active work zones: knitted or extruded HDPE mesh on rolls, plus posts, ties and gates that complete the system. The mesh is the commodity; the fence is the installed assembly, and buyers who quote per roll while ignoring post spacing end up with a line that sails in the first real wind.
Standard hdpe barrier fence rolls run 50 m long at 1.0, 1.2 or 1.8 m height, weighing 4 to 9 kg each. Orange safety mesh is the default: it reads against snow, greenery and urban grey, and pigment is compounded with UV inhibitors so colour holds through a season.
Knitted versus extruded mesh
Knitted mesh is built from interlocked continuous filaments: light, flexible and tear-resistant, the usual choice where the line moves between phases. Extruded mesh is pushed through a die as a sheet, giving a more rigid panel with a heavier hand that holds shape on longer deployments. Surface weight tells you more than adjectives: general-duty mesh sits near 100 g per square metre, heavier knitted grades for high-wind sites run higher, with reinforcing bands woven along the roll to stop sag.
Engineering the line for wind
Wind is the design case. Oval apertures let air through instead of catching it, but the post is the limiting component: steel T-posts or rebar stakes driven at least 450 mm into the ground, spaced about 3 m at standard height and 2.4 m where exposure is higher. Tie the mesh top, middle and bottom of every post, and weight the bottom edge with sandbags or staples against gusts. US practice asks for orange HDPE mesh at minimum 1.2 m height, openings no larger than 50 mm, and a fence taut under about 90 kg of push with less than 100 mm of deflection - a useful benchmark for any RFQ.
Applications and packaging
Road and paving projects, utility trenching, demolition drop zones and event crowd control account for most temporary fencing volume. Contractors value the two-person install rate - several hundred metres per hour - and clean removal. Rolls ship nested in woven bags, typically 10 to 20 per bale; confirm rolls per 40HQ for landed-cost comparison.
What to confirm with a plastic barrier fence manufacturer
- Knitted or extruded construction, surface weight in g per square metre, and mesh aperture in mm.
- Height and roll length options, and whether reinforcing bands come in heavier grades.
- UV stabilisation and low-temperature flexibility if the fence winters on site.
- Post, tie and gate supply - mesh-only quotations shift the real cost to accessories.
- Bale packing, rolls per container, and colour options beyond standard orange.
