Our Manufacturing

Much of Sonic Steel’s manufacturing begins with wire. Imported raw wire arrives at the facility in coil form and, where required, is prepared in-house to the production diameter needed for the next stage. A 6.5 mm wire, for example, can be cold drawn to 6.0 mm before moving further into production.

From there, the route depends on the product. For wire nails, prepared wire feeds into the nail-making line, where each nail is cut and formed to the required length, with the head and point created as part of the machine cycle. BRC and GI welded mesh follow a different process: one direction of wire is positioned by the operator while the machine feeds the intersecting wire and completes the welding cycle, building the mesh panel intersection by intersection.

GI barbed wire is produced from galvanized wire, which is twisted and formed into the final fencing product. Alongside these manufactured lines, the facility also handles cut-to-length processing — including straightening and cutting MS wire rods and processing selected steel coils and sheets to required lengths.

These activities sit within the same Dankotuwa facility, allowing material preparation, manufacturing, processing, finished-goods handling and storage to remain closely connected. The result is a focused operation built around a defined range of wire-based products and steel processing services rather than an overly broad catalogue.
