Hoarding, guardrails and wire mesh fencing — made in Wuhan since 2014

What the three families do, and how they combine on one site

A finished site is described in three layers. Hoarding and site fencing closes the work area to the public: panels, posts, braces and bases, plus the water-filled barriers that divert traffic around it. Guardrails and railings protect what is open or at height — an excavation edge, a slab edge, a carriageway or a crowd — and are the items a safety inspector looks at first. Wire mesh fencing holds a boundary over the long run: a plant perimeter, a rail corridor, a school or a sports court.

The three are ordered together far more often than separately, and that is the practical reason to buy them from one workshop. A single site typically needs hoarding on the street frontage, mesh fence on the rear boundary, guardrail around the excavation, and a barrier where the traffic has to be diverted. Because all three are made in Jiangxia, they can be quoted as one programme, drawn to one set of site dimensions, packed on one loading plan and shipped on one bill.

Two rules of thumb keep a mixed order clean. Decide the ground fixing before the panel, because a post set in concrete, a base plate on a slab and the foot of a hoarding panel are three different products. And give the run lengths in metres with the corner and gate positions, because every family is counted from a run, never from a square metre.

How to choose hoarding: height, panel, base, wind

Height is set by the works behind the panel and by the local rule, not by preference. Our published hoarding panels start at a 1,200 × 2,000 mm perforated sheet and run to 2.5 × 6 m printed sections. The taller the run, the more of the wind load is carried by the post and the brace rather than by the panel, so height and bracing are decided together.

Panel choice follows what the frontage has to do. Colour-steel sheet at 0.3 mm is the light, fast option. A 20 mm PVC board gives a solid coloured face. Perforated galvanised sheet at 0.5–0.8 mm lets wind and light through and takes an electrostatic spray in the colour you choose. A printed section carries an image instead. Base and fixing come next: flange plates and expansion bolts for a concrete slab, a 400 × 300 × 110 mm precast concrete base where the run is temporary and has to come down again, and the detail on the drawing where the ground is neither.

Wind is the last question and the one that fails first. Bracing is what keeps a run standing: 50 × 50 × 0.9 mm square tube on municipal hoarding, 40 square tube or L40 on colour-steel, a galvanised channel and 40 square tube on PVC. Where the hoarding is replaced by a plastic barrier, the tall water-filled type is rated to wind force grade 7–8 and is ballasted with 100 kg of water per unit.

How to choose guardrails: edge protection, road barrier, railing

Three different jobs, three different products. Edge protection keeps people away from a drop: the excavation edge guardrail, in a mesh-panel build on a 20 × 30 / 30 × 30 mm frame with 50 × 50 mm mesh, or a vertical-tube build on a 30 × 30 mm frame, both on a 50 × 50 mm square-tube post. A road barrier takes a vehicle impact and guides it along the beam. A railing separates people from a boundary, a planter or a green strip and is chosen as much for its appearance as for its stiffness.

The road barrier is where the range splits into two products that are never interchangeable. W-Beam Steel Road Guardrail is the standardised corrugated-beam system: 4320 mm panels on a 4 m post spacing, twin-wave 310 mm or triple-wave 505 mm wide, 85 mm wave height, 3 mm or 4 mm plate, on Φ114 / Φ140 mm posts with a 4.5 mm wall, and its published figures cite JT/T 281—2007. Road Guardrail is the general road and municipal line: roadside and median barrier units, beam and rail sections, posts and fixings made to the project specification. No JT/T figures are quoted for it, because it is not that system.

So the question is not which one is better, but which one the project is written against. If the specification names JT/T 281—2007 or a corrugated beam with a panel length and a post spacing, we quote the W-beam product from its published figures and state what a kilometre contains. If the drawing shows a municipal barrier, a median unit or a rail section to the authority's own detail, we quote the road guardrail product and build to that drawing or standard. The two have separate product pages, separate specifications and separate quotations, and a beam from one is never supplied against the other's drawing.

How to choose wire-mesh fencing: aperture, post type, height

Aperture is the first decision, because it sets what the fence keeps in or out. On our framed mesh panels the common apertures are 50 × 100, 75 × 150, 50 × 200, 60 × 150 and 80 × 160 mm; wire runs from ø2.5 to ø6.0 mm, most often ø3.0, ø3.2, ø3.5, ø3.8 or ø4.0 mm. Other mesh builds — chain-link, Y-post, sports court — are made to the project specification: send us the drawing or the standard you follow, and we confirm the aperture and the wire in writing.

Post type follows the load and the ground. Round ø48 mm tube is available with a 1.0, 1.2, 1.5 or 2.0 mm wall, with 60 mm and 75 mm tube as alternatives; square tube runs 40 × 40, 60 × 60, 40 × 60 and 80 × 80 mm with a 0.8–2.0 mm wall. Post spacing is confirmed against the drawing rather than assumed, and the fixing — clamps, clips, tension bands, base plates or concrete footings — is quoted with the run.

Height comes last because it is the easiest to change and the most expensive to get wrong. Framed panels are published at 1700 × 2500, 1800 × 2500, 1800 × 3000, 2000 × 3000 and 1500 × 2500 mm. A school or a sports court needs more height than a plant boundary, and an anti-glare mesh is set at the height of the headlights it has to cut, not at a standard fence height.

Quotation and documentation

No price is published on this site, and no MOQ or lead time is promised before the specification is known. Every figure we can give depends on three things: the drawing or the standard, the quantity and the destination port. Send those three, add the finish and the delivery address if they are already fixed, and we reply within one business day with the specification, the coating, the packing plan, the MOQ, the loading plan and the lead time in writing.

Documentation is issued per order: proforma invoice, commercial invoice, packing list and certificate of origin as required. Payment terms and warranty are agreed per order and stated on the proforma invoice.

On standards, we will not claim a certificate we do not hold. Buyers who need CE / EN / ASTM documentation: tell us the standard and we will confirm in writing what we can supply.

Packing, loading and lead time

Panels, beams and posts are bundled and palletised; fittings — clips, post caps, spacer blocks, bolt sets — are bagged and bundled separately and labelled against the drawing. The exact packing method is confirmed per specification with the loading plan, because a bundle that cannot be unloaded at destination is not a saving.

Loading is a weight question before it is a volume question. Steel barrier is heavy for its volume, so the published masses are the figures that decide the plan: 49.16 kg for a 3 mm twin-wave panel and 65.44 kg for a 4 mm panel, 102 kg for a triple-wave panel, 12.15 kg/m for a Φ114 mm post and 15.04 kg/m for a Φ140 mm post, with 12.3 t or 16.388 t of beam in a kilometre at 3 mm or 4 mm plate. Give us the container size, the beam type and the maximum bundle weight you can unload, and we plan to it.

Lead time is confirmed per specification, not published as a promise: send the drawing, quantity and destination port and we reply with MOQ, loading plan and lead time within one business day. We would rather give you a date we can hold than a number that reads well in an enquiry.

Six questions, answered from what is on this site

Are you a factory or a trading company?

A factory. We produce at our own workshop in Jiangxia District, Wuhan, and have manufactured there since 2014: a 5,000 m² workshop with a 2,000 m² finished-goods warehouse beside it, a monthly capacity of 60,000 m, and registered capital of RMB 5 million.

What is the difference between the W-beam steel road guardrail and the road guardrail?

They are two separate products. The W-beam steel road guardrail is the standardised corrugated-beam system, published against JT/T 281—2007: 4320 mm panels, 4 m post spacing, twin-wave 310 mm or triple-wave 505 mm beams, 85 mm wave height, Φ114 / Φ140 mm posts and stated quantities per kilometre. The road guardrail is the general road and municipal line — barrier units, beam and rail sections, posts and fixings made to the project specification, with no JT/T figures quoted for it. Send the drawing or the standard and we quote the one that matches it.

Can I order hoarding, guardrails and mesh fencing together?

Yes. All three families are made in the same workshop, so a mixed order is quoted as one programme, drawn to one set of site dimensions, packed on one loading plan and shipped on one bill.

What do I need to send to get a quotation?

The drawing or the standard you follow, the quantity or the run length, and the destination port. Add the finish, colour and delivery address if they are already fixed. With those we reply with the specification, MOQ, loading plan and lead time within one business day.

Do you supply CE, EN or ASTM documentation?

Buyers who need CE / EN / ASTM documentation: tell us the standard and we will confirm in writing what we can supply. The documents issued per order are the proforma invoice, commercial invoice, packing list and certificate of origin as required.

Have you supplied projects outside China?

Our record is municipal and metro construction projects in central China since 2014. For an export order the same workshop, the same drawings and the same inspection apply; we confirm in writing what we can supply rather than claim references we do not have.
