Quality Assurance &Control

In order to enhance the quality of the precast concrete accessories, we use two techniques:Quality Assurance (QA) and Quality Control (QC). These two practices make sure that the final product meets the stipulated quality requirements and defined standards.

The truth is that both concepts have strong interdependence. QA relies mostly on the QC feedback and both work to deliver good quality products but they are different processes.

Although QA and QC are closely related concepts and both are aspects of quality management, they are fundamentally different in their focus:

  • QC is used to verify the quality of the output

  • QA is the process of quality management

Key Point

​

QC Responsibility
Our QC in manufacturing highlights the importance of thorough examination and testing of the product quality to find defects.

​

the Raw Material 

1.All of the raw materials are sourced from the certified steel works directly with the qualified test report.
2.The raw material samples are selected randomly from bulk goods before the bulk production and then submit to make microscopy and hardness tests to analyze their structure, composition etc., and match with the standard to make sure the raw material was qualified.

​

Inspection for Dimension
The first batch of bulk products are checked on the worktable according the technical drawing. During the production, the special inspection tools are applied to control the Dimension.

​

Mechanical testing
Before the delivery, we need the report to reassurance and certify that our precast concrete accessories were qualified for an intended use, such as lifting, connection or meets the customer’s specifications.Mechanical testing uses impact, tensile and hardness testing to safety of our precast concrete accessories.The testing is an integral process to test our metal or alloy products performs under exacting conditions and whether it complies with the qualified products standards.
