About Us


Andrew Mentis (Pty) Ltd was first formed in 1950 as a precision engineering workshop and subsequently went into the development and manufacture of steel grating. In 1959 Gripweld grating was produced in South Africa by Andrew Mentis, followed by the unique Rectagrid grating, in 1967. Through continual research and development, Andrew Mentis (Pty) Ltd has become a leading manufacturer of grating.

The company has been successful in gaining a share in overseas markets, and locally has supplied vast quantities of quality products to all of the major industries including power generation, mining, petrochemical, motor, construction, food, paper and steel.

In addition to grating, the company offers expanded metal, Mentrail (guard-rails for roads), Mentcano (perforated steel sections), industrial handrail systems, steel floor tiles and Mendrill (automatic drilling and boring machines).
In 2012 Andrew Mentis (Pty) Ltd acquired R & R Engineering (WA) Pty Ltd.

R & R Engineering started in 2000 in the hills of perth and quickly became the handrail fabricator of choice, through quality workmanship, to some of the leading Construction and Project Engineering Companies in WA.

To maintain a quality product, R & R installed the latest Robotics Welders and designed its own Stanchion Drilling Machine. Coupled with one of the latest auto bending Machines available in the world, R & R is able to offer a firm commitment to delivery schedules for standard and non-standard handrail, at competitive rates.

All Stanchions are designed to Australian Standards 1657 and dedicated Robotic Welders ensure uniformity and quality in all our welds, which conform to AS 1554 SP.

In 2006, R & R successfully entered the Grating and Tread fabrication market as a direct result of customer pressure to compliment the R & R handrail.

Now with the combined experience and quality driven reputation of both companies united, you can be rest assured of Quality Service Innovation.

In June 2015 Mentis acquired Rhino-grating, a handrail and grating fabricator with facilities in Queensland, Victoria, New Zealand and China. Rhino-grating has been operating since the early 2000’s and has similar values to Mentis based on quality and service.

The Mentis story is one of continued growth through partnerships with suppliers and customers alike. Join us as we make history in the endless pursuit of Quality, Service and Innovation.
