Ma Ga’s products are satisfied with relevant Quality Control and Assurance system. In-house design team and quality control team work together and set production specifications. Our production Specifications shall meet to international specifications and local requirements. All Ma Ga’s products are tested and satisfied by total quality control system. Only qualified products shall be issued to our valued customers.
Production Quality Control
Geometric checking of moulds are carried out according to approve specification, prepared by in-house design teams. Quality control teams check the tension of pre-stressed steel wires by using of tensionometer. Then mix the concrete with quality raw material for casting into the moulds.
Curing compounds are applied when concrete became final setting. Stressed steel wires are cut when concrete strength achieve to 30 MPa. Transporting the concrete products are allowed when concrete strength achieve 35 MPa.
Concrete products are systematically sampled and tested in government laboratories. Prestressed hollow concrete poles are tested in laboratory owned by Ministry of Electricity (2). Prestressed concrete beams and slabs are tested in Yangon Technological University.
Quality control team checks and tests systematically on production and raw material, batch by batch. Only quality approved products are supplied to our valued customers.
The cements are tested with British Standard 12 and only approved cements are used for our products.
High Tensile Steel Wire
Application of high tensile steel wire in precast concrete products are not common in Myanmar. Ma Ga uses the steel wires with the yield strength more than 1600 MPa. The steel shall be hot rolled and low relaxation.
Over reflection due to relaxation of steel are very common in Myanmar. Ma Ga takes note on this matter and improves our products quality to avoid those.
Coarse and Fine Aggregate
Fine and coarse aggregates are tested by British Standard (812) . Ma Ga only uses the aggregates of which qualities meet British Standard 812’s requirements.
Ma Ga uses concrete admixture designed specially by poly carbonxylate base which is 3rd generation chemicals. In some products, Ma Ga uses polymer reinforced system and increase flexural strength. Those products shall be suitable in seismic risk area and higher wind loading risk area. Our in-house chemical deparment design and fomulate construction chemicals especially for precast concrete products.
