クォリティー List of Products and Services

Our company conducts various environmental surveys, and we already have extensive experience in measuring indoor environments for sick house, sick school, and sick building during new construction and renovation, providing our customers with highly reliable measurement results. We cater to a wide range of requests, from individuals concerned about sick house issues in their homes to construction contractors who need to report measurement results to the relevant authorities. In addition, we also conduct vibration surveys and noise surveys. [Survey Examples] ■ Sick House ■ Vibration Survey ■ Noise Survey *For more details, please refer to the PDF materials or feel free to contact us.

• Environmental Survey

Our company conducts durability assessments of existing structures, investigating and examining the current state and causes of damage and deterioration, and proposing policies and measures based on future predictions. Concrete structures are considered to have a semi-permanent lifespan; however, cracks can occur due to various causes such as earthquakes, leading to phenomena such as carbonation, salt damage, and alkali-silica reactions, which can cause rebar to rust, concrete to crack, and in some cases, concrete to spall, exposing the rebar. Additionally, detecting the position of steel frames and rebar within concrete structures is essential for maintenance management. Our company utilizes advanced technology to detect surface cracks and internal damage at an early stage, providing documentation to maintain the safety and quality of the structures. [Testing Examples] - Investigation of rebar placement and cover thickness - Tensile testing of tiles - Sampling of concrete core specimens - Carbonation testing of concrete *For more details, please refer to the PDF document or feel free to contact us.

• Structural Survey

Our company conducts quality inspections and tests of concrete and steel materials, as well as soil investigations. Additionally, we handle preliminary surveys of structures, environmental investigations, and consulting services. We also perform steel testing and possess numerous testing machines. In tensile tests, we set a specimen of rebar or structural steel in the testing machine, apply tension along the axis of the specimen, and measure the force applied until the specimen typically fractures, determining the yield point and tensile strength. We conduct quality testing and management of steel materials using various testing methods. 【Examples of Tests (Partial Excerpt)】 ■ Tensile Test ■ Static Elasticity Test (Young's Modulus) ■ Bending Test ■ Ultrasonic Testing (UT) ■ Unit Mass Test, etc. *For more details, please refer to the PDF materials or feel free to contact us.

• Steel

Our company conducts quality inspections and tests of concrete and steel materials, as well as soil investigations. Additionally, we handle preliminary surveys of structures, environmental investigations, and consulting services. We deal with various investigations related to soil, and to ensure a solid foundation for structures, we conduct tests on soil and ground bearing capacity, sounding tests of supporting ground, and plate load tests of the ground, among other foundational ground investigations. 【Examples of Tests (Partial Excerpt)】 ■ Soil and ground bearing capacity tests ■ Uniaxial tests of soil ■ Sounding tests of supporting ground ■ Plate load tests of the ground ■ Simple load tests (Caspole), etc. *For more details, please refer to the PDF materials or feel free to contact us.

• Geological Survey

At Quality Co., Ltd., we conduct "non-destructive testing" to examine internal and surface damage without breaking objects, as well as "seismic diagnosis surveys" for structures. Non-destructive testing is applied to inspections during the processing of materials and upon completion of products, as well as during the construction of equipment, thereby enhancing the reliability of products and equipment and helping to extend their lifespan. Additionally, seismic diagnosis surveys utilize non-destructive testing techniques to detect even invisible internal damage. 【Seismic Diagnosis Survey - Diagnostic Items】 ■ Measurement of member dimensions ■ Ultrasonic flaw detection testing ■ Investigation of rust conditions ■ Concrete investigation ■ Visual inspection, etc. *For more details, please download the PDF or feel free to contact us.
