Since 1962, Prestressed Concrete Pile of General Engineering Public Company Limited are well-known and widely accepted. Prestressed Concrete Pile is a quality product, being used for ground works of various forms of building , that help reduce construction duration and cost of construction very well, especially, for the areas of soft soil in Bangkok Metropolitan Region. Over the past 53 years, the company has produced precast prestressed concrete piles more than two million piles, which reflects the quality of precast prestressed concrete pile under GEL brand.
GEL has the management team that are full of skills and experience, having its keen determination to do the business by focusing on quality and service. The company is monitoring the development of production processes continuously and is very selective on the quality material. Currently, the products of the company has been awarded the marks of Thailand Industrial Standard - TIS. 396-2549. In addition , the company also has other products such as Concrete Sheet Pile to accommodate demand of construction works in the government and private sectors.
Concrete with compressive strength when it is tested at 28 days of not less than 350 kg. /sq. cm. for the sample of cylinder shape concrete at a diameter of 15 cm. and at the height of 30 cm.
Cement used is Portland cement under category 3 which generates quick compressive strength under ASTM C150 standard and TIS. 15 , Volume 1, - 2004.
Concrete admixtures , according to the ratio set by manufacturer to aggregated concrete used in the production to obtain aq high compressive strength in a given period.
Clean and good quality of sand and stone materials from good source of raw material so that various mixtures can capture together well and have high compressive strength.
Production is in compliance with production process of Prestressed Concrete before pouring concrete.
Compressive strength of the concrete must be less than 250 kg / sq. cm. to enable to produce Prestressed Concrete.
Go through the curing process with water 3-7 days before it can be delivered to the construction site for drilling.
