Top Tubes’ ERW Division is a manufacturing stockholder of seam welded mild steel tube.
Offering service levels of a distributor allied with the backup of in-house production, we offer the competitive pricing of a manufacturer along with market leading supply flexibility.
Our motto is to be “easy to buy off”. If you buy full packs of ERW mill lengths, or exact/cut lengths, then we are uniquely placed within the market to be your ideal supply partner.
Top Tubes operates two modern ERW tube mills that have the capacity to produce 50,000 tonnes per annum. A wide variety of specifications are available in terms of mechanical & chemical properties to match bespoke customer requirements.
Our length capability, directly off the ERW tube mill, ranges from 2000mm to 13500mm, all with clean cut sheared ends.
Incorporated into Top Tubes production lines is our unique slit coil edge preparation technology. Through precise edge profiling and surface treatment this process yields a finished tube with superior weld strength and integrity. Stronger, in fact, than steel itself.
