Alloy Steel International (ASI) is an independent international company with its manufacturing facility and head office in Perth, Western Australia.

ASI has developed a good market presence since it began manufacturing Arcoplate in 1991.

The main focus for the team at ASI is to produce protective wear plate to assist in maximising production while reducing costs of repairs and maintenance for our customers. Arcoplate is produced in various grades and thicknesses to ensure we have plate suitable for different applications. Continuous improvement is a must, that is why we have a team of metallurgists and engineers developing Arcoplate and our other wear materials.

The late Mr. Gene Kostecki was the creative genius responsible for the invention of Arcoplate. At the time of his invention, Mr. Kostecki was immersed in the mining industry in Western Australia. He identified the need for an innovative wear solution to improve the productivity of mining companies worldwide. After five years of experimentation and development on a prototype mill, Arcoplate was born.

The manufacturing of Arcoplate began in 1991, with the first commercial sale being achieved in the same year. Arcoplate’s first sale was the 305cm (12”) wide plate format and was produced on the original prototype mill. This model had been modified to allow for both commercial production as well as continuing research, design and product improvement.

Australian orders grew significantly in the first two years of operation. Then in 1993, the first export order was received from the United States. This represented a momentous break through. The young Australian company, Arcoplate, had launched into the international wear plate market. With continuing demand for Arcoplate, Alloy Steel International (ASI) of Australia developed and manufactured its own in house production plant to produce 305mm and 610mm wear plates in multiple product thicknesses. To ensure consistent product quality, ASI continues to develop and manufacture all of its own production plant and processes in house.

Following market trends and an overwhelming demand from the mining industry, ASI designed a manufacturing plant able to produce wear plate in thicknesses up to 20/11 and in a 1270mm width. Arcoplate is currently exported to over 25 countries worldwide and has qualified representatives, office locations and distributors in the United States, Chile, India, and throughout Australia.

To this day, Mr. Kostecki’s passion continues on with his son, Steven Kostecki as Managing Director and Chief Executive Officer of Alloy Steel International. Together with other members of the Kostecki Family, the business continues to grow in Australia and Internationally.
