Traffic signs · aluminium · barriers
six product lines, one chain
From coil to a fully sheeted sign, from clamp bolts to a complete sound barrier run. Full package or single-process processing.
01 / Aluminum
Aluminium sheet & coil
Four grades held in stock: 1060, 3003, 3004 and 5A02. The grade sets strength, formability and corrosion life — we advise on the trade-off at selection stage.
| Grade | Positioning | Stock size | Factor |
|---|---|---|---|
| 1060 | Pure aluminium, 99.6% Al. Best formability and corrosion resistance. | 2.0 / 3.0 mm · 1000–1600 mm | 2.71 |
| 3003 | Al-Mn alloy. Outstanding rust resistance, good forming and welding. | Cut to order · 1000–1600 mm | 2.73 |
| 3004 | Higher strength than 3003; used where greater stiffness is needed. | 2.0 / 3.0 mm · 1000–1600 mm | 2.73 |
| 5A02 | Al-Mn系. High fatigue strength with good ductility and corrosion resistance. | 2.0 / 3.0 mm · 1000–1500 mm | 2.73 |
Weight estimate: L(m) × W(m) × T(m) × factor = tonnes. Sizes above are standard stock; cut-to-length and special thickness are made to order.
02 / Extrusion
6063 profiles
6063 is an Mg–Si extrusion alloy with excellent extrudability, weldability and finishing — the standard choice for sign stiffeners, grooves and curtain-wall frames. Four extrusion lines; sections and lengths made to order.
| Item | Specification |
|---|---|
| Groove thickness | 2.0 / 3.0 / 4.0 mm |
| Groove width | 60# / 70# / 80# / 100# / 110# |
| Temper | T5 |
| Main elements | Mg 0.45–0.9%, Si 0.2–0.6% |
| Matching parts | Clamps, retaining blocks and square-head bolts from the same plant |
03 / Signage
Traffic signs
A 10,000 m² workshop, 10,000 m² per month, about 1,500 m² per day. Finished, semi-finished and illuminated — completed in one workshop.
Finished signs
Sheet cutting, edge bending, groove riveting and sheeting applied — installable on delivery.
Semi-finished
Bent sheet plus riveted groove, for factories that apply their own sheeting — balancing cost and lead time.
Illuminated signs
With active illuminated panels for tunnel portals and ramps where visibility demands more.
| Process | Equipment | Qty |
|---|---|---|
| Coil levelling | Leveller | 2 |
| Trimming | Shear | 1 |
| Edge bending | Press brake | 2 |
| Corner cutting | Corner press | 4 |
| Groove welding | Laser welder | 2 |
| Groove riveting | Riveter | 4 |
| Disc / triangle forming | Press | 4 |
| Sheet cutting | Laser engraver | 1 |
| Sheeting plotter | Plotter | 2 |
| Route-name welding | Laser robot arm | 1 |
Sheeting comes in five classes, I (lowest) to V (highest), matched to road class and service life.
04 / Structure
Posts & large gantries
A 30-mu structural shop with in-house hot-dip galvanizing. Daily output of 50 t of posts and cantilevers, or 15 large gantries. Flanges, stiffeners and holes assembled to drawing, with dimensional checks before dispatch.
| Component | Typical size |
|---|---|
| Post | φ273 × 8 × 7300 |
| Beam | φ133 × 8 × 2300 |
| Base flange | φ550 × 20 |
| Beam flange | φ300 × 16 |
| Finish | Hot-dip galvanizing (also toll processing) |
| Standard | GB/T 23827-2021 |
05 / Acoustics
Roadside sound barriers
Reflective types block sound; absorptive composites combine absorption with insulation and work better. Panel material is a balance of appearance and budget.
Barriers serve highways, expressways, elevated roads and other noise sources, supplied as a set of panels, posts, connectors and foundation embedments.
06 / Accessories
Accessories
One place, one fewer supplier. Clamps, bolts and retaining blocks are made in-house; sheeting and road furniture supplied as a set.
Clamps
Three types: 50/5 national-standard hot-dip, 40/4 hot-dip and 30/3 electroplated. National-standard clamps use Q235 plate, punched, sheared, formed and hot-dip galvanized.
Sizes：φ76 / φ89 / φ114 / φ121 / φ140 / φ152 / φ159 / φ168 / φ180 / φ203 / φ219 / φ273 / φ325 / φ351 / φ377
Bolts
| Size | Head / pitch | Fits groove ID |
|---|---|---|
| φ12×60 | 20 / 20 | 21–28 mm |
| φ16×70 | 30 / 40 | 32–42 mm |
| φ18×80 | 30 / 40 | 32–42 mm |
| φ18×50 | 30 / 40 | Retaining block |
Retaining blocks and small parts
Retaining blocks use 6061-T5 aluminium: extruded, punched and cut to length.
Reflective sheeting
| Class | Structure | Life | Typical use |
|---|---|---|---|
| I 类 | Embedded glass bead | 7 yrs | Rural roads, car parks |
| II 类 | Embedded glass bead | 10 yrs | County roads, low-speed streets |
| III 类 | Sealed lens | 10 yrs | Provincial roads, campuses |
| IV 类 | Microprismatic | 10 yrs | Provincial roads, expressways |

Blow- and rotomoulded crash barrels and water barriers, indoor/outdoor convex mirrors, PE/EVA/PU flexible delineators, rubber and PU speed humps, traffic cones (custom text), PU wheel stops and corner guards.
FAQ
Product questions
What is the minimum order quantity for signs?
Orders from a few hundred to tens of thousands of square metres are accepted, including small trial batches used to verify process and fit. The same quality standard applies.
Can I buy aluminium sheet without processing?
Yes. 1060, 3003, 3004 and 5A02 are held in stock and can be levelled and cut to length only, leaving later operations to you.
Can you make non-standard and shaped signs?
Yes. Dedicated dies cover triangular and circular blanks; other shapes are cut to drawing. Send a drawing or sample and we will confirm feasibility and tooling cost.
