For building and construction, the division offers the flexibility of two galvanizing lines:

Line 1 features the longest kettle in South Africa. The line is a general open dip facility, specialising in the galvanizing of long products, such as large bore piping, lighting poles, structural steel and fabricated sections.

Line 2 is the widest and deepest galvanising kettle in South Africa, offering corrosion consultants, engineers, designers and fabricators much needed flexibility on the corrosion protection of steel. The line is ideally suited to pipe-work, fencing panels, box frames, chutes, staircases, ducting, large vessels and receivers, as well as long products which are less than 3.7m long. These can be vertically dipped.

Value added services:

  • Transport – collection from fabricators and deliveries to site
