Manufacturing & quality
One factory, from steel coil to sealed export crate.
Forming, welding, machining, galvanizing, coating and packing all happen on our site. Nothing critical is sub-contracted, so quality and lead time stay under our control.

The production line
Seven stations, one traveller sheet per pole.
Cutting & forming
Steel plate is guillotine-cut to a taper pattern, then folded on a 12 m press brake (octagonal) or rolled (conical). Every blank is traceable to its mill certificate.
Longitudinal welding
The shaft seam is closed by automated submerged-arc welding for a consistent, full-penetration weld. Welders are certified to ISO 9606-1.
Base plate & door
CNC-cut base plate is fitted and fillet-welded with gussets; the inspection door frame, earthing stud and cable entry are added.
Weld inspection
Visual inspection on 100% of welds; magnetic-particle or ultrasonic testing on base-plate welds and on any batch the client specifies.
Hot-dip galvanizing
Degrease, acid pickle, flux, then immersion in molten zinc at ~450 °C. Average coating 70–85 µm to ISO 1461, verified with an electronic gauge and logged per batch.
Coating (optional)
Where specified: chromate-free passivation, epoxy primer and polyester powder top-coat in any RAL, for a duplex system on coastal or decorative projects.
Final check & packing
Dimensional check against the drawing, straightness, thread and fit-up of accessories; then padded, nested and steel-strapped for sea freight with a photo record.
Quality control
What every shipment is checked against
- Raw-material mill certificates (EN 10204 3.1) kept on file per pole batch
- Welder qualifications and weld procedure specifications (WPS/PQR)
- Galvanizing coating-thickness report for each batch
- Dimensional and straightness inspection record against approved drawings
- Third-party / SGS pre-shipment inspection welcomed and accommodated
