Premium Quality Calcined Bauxite for High Friction Surfacing

I am a Business Representative for Ashapura and associate company Orient Abrasives Ltd. Established in 1960 the group is India’s largest muti-mineral solutions supplier & supplier of Calcined Bauxite.




Orient Abrasives Ltd. (OAL) provide high quality competitively priced Calcined Bauxite for High Friction (Anti-skid) Surfacing.  With it's very high PSV. and exceptionally low AAV, OAL's Calcined Bauxite is the ideal product for incorporation in long lasting durable HFS systems. Over the last number of years, OAL have supplied thousands of tonnes to the UK & US for HFS installation. More recently, they have supplied product for the Australian & New Zealand HFS markets. The group's proximity to ports and the fact that they own their own port and fleet of ships gives them the competitive edge in today's challenging  market environment, where costs, quality and time are of the essence. Ashapura & associated companies have the scale & logistical capability to efficiently produce & deliver large quantities of product. 

Calcined Bauxite is obtained by calcining (heating) superior grade Bauxite at high temperature, which removes moisture, thereby increasing the alumina content. Compared to an alumina content of about 57 % to 58 % in raw Bauxite, Calcined Bauxite has an alumina content (Al2O3) of 84 % to 88 %. The heating is carried out in rotary kilns and is calcined at temperatures from 1200º C - 1800ºC. The calcination plant is situated at Jam-Khambaliya in Saurashtra region (India) with an annual capacity of 100,000 tonnes. The plant is within a radius of 50 kms to major international ports.   

Typically supplied in 1-3mm grade, the Calcined Bauxite complies with Clause 924, BBA/HAPAS Type 1 and TII (formerly NRA) requirements. Other sizes are available on request. Product can be supplied direct from India in container loads (typically 25 tonne) at very competitive prices. For more urgent orders in Europe, a limited stock is kept at the group's warehouse in Antwerp, where the lead time should be less than a week.

It is available in three colours.

PB 1000 - A dark grey stone which does not provide a significant colour contrast with a typical asphalt road

CA 1000 B - A buff pigmented version of PB 1000

PB 500 - A whitish buff stone. Good for decorative applications where skid resistance is important.
