Intermine Agencies was established inWelkom in 1983 to supply steel pipe, flanges and fittings to the Gold Mining Industry. The success of the organisation progressed into an expansion that saw the establishment of a specialist workshop that catered for the fabrication of piping used in plant and overland pipelines. This workshop further developed the capability to corrosion protect this piping. This unique capability gave Intermine Agencies the opportunity to expand its product offering into the Civil Engineering sector, supplying fabricated piping used for water reticulation projects countrywide. The expertise developed by Intermine Agencies in the fabrication of its products created a demand for the fabrication and onsite installation of steel supporting structures. In 1999, an experienced team of construction specialists was formed to install fabricated items on-site for our clients.

The primary component supply and the fabrication of piping and steel continues to be focussed in our Welkom facility. In 2000 the expansion of our product demand in the Platinum Industry led to us establishing a branch office in Rustenburg to directly service our customers in this region.

Intermine Agencies has over its almost 30 years built a proud history of supplying high quality product and components to a demanding customer base. Key to our success has been our dedication to the completion of work that it has undertaken on time and within budget. Recent projects include:

• Erection of a 77m GRP stack with support steelwork
• Fabrication,supply and erection of Toll Handling facilities including, buildings comprising cellular beams and all sheeting and mechanical items.
• Fabrication and erection of a tailings plant, including supplying and laying rubber lined pipelines, thickeners and mixing tanks.
• Manufacture and site erection of 1100m3 storage tanks.

• Six In line furnace rebuilds and maintenance.
• Converter and furnace fugitive/off-gas duct work including structural supports.
• In-plant and overland pipelines.
• Supply, fabrication and corrosion protection of piping in both carbon and stainless steel for various water authorities and contractors involved in water reticulation.
• Bulk Air Cooler pipework,structural and mechanicals.

Our combined expertise in piping,structural steel and sitework will complete your project with the highest regard for safety, engineering standards, costs and quality.
