Santa Rosa Factory
Manufacturing and Supplying Highly Reliable Industrial Products Based on Rigorous Quality Control
Although "Taihei Alltech Construction(Phil.),Inc.", a joint venture between Taihei Dengyo and Alltech Corporation of the Philippines, had already built up considerable experience in the installation of thermal power stations and chemical plants petrochemical plants, the company constructed its Santa Rosa Plant in September 1990 in Santa Rosa in the Laguna province of the Philippines to expand and strengthen the functions associated with plant installation work.
The Santa Rosa Plant is involved in the manufacture of steel-frame structures for various plants, sheetmetal work such as absorption towers, tanks and ducts, pipework prefabrication, and the fabrication of cable trays and cable ducts for use in the Philippines and elsewhere.
To improve the capabilities of engineers and skills of technicians, the plant sends several tens of trainees to Japan each year where they can improve their skills at Taihei Dengyo's Saitama Plant. Under the tutelage of Japanese supervisors, the trainees learn how to produce high quality products and earn the high regard of their customers through rigorous quality control and systems for ensuring that projects are delivered on time.

Main Activities

Santa Rosa Plant is set up to undertake a full range of work from the preparation of working drawings and full-scale plans through to marking, cutting, assembly, welding, finishing, surface preparation, painting, packaging, and dispatch.
In each process, work is carried out under the supervision of highly experienced veteran engineers from Japan to ensure the delivery of high quality products. This includes, in the welding process for example, taking extreme care with inspections under the instructions of Japanese engineers with welding qualifications (CWI) from the American Welding Society (AWS), along with increasing automation and rationalization of welding work.
