The quality inspection of Precast concrete Lifting & Fixing Sockets (Inserts) includes: raw materials, tensile properties, size, quantity and other inspections. These four items are crucial to you because they determine whether they can be used normally. A good supplier will provide a detailed inspection report. Please be sure to communicate this before placing an order.
Every insert undergoes dimensional inspection using vernier calipers and thread gauges. We double-check thread depth, outside diameter, and critical lengths—even if it takes a bit more time.
This is where things get serious. Random samples are pulled using a certified tensile testing machine—and we test beyond the working load limit, using a 3 times safety factor to simulate worst-case conditions. If it breaks too early? That batch doesn't go out.
For projects with higher technical standards or compliance requirements, we offer a variety of optional testing services. These include salt spray testing, coating thickness measurement, ultrasonic flaw detection, metallographic analysis, and third-party inspections. If your engineers or clients require additional certifications, just let us know during the inquiry stage.
To avoid under- or over-shipments, we use batch weight calculations and piece-by-piece counts. It's not glamorous, but accuracy here saves everyone a lot of hassle later.
All incoming steel tubes or rods are tested for mechanical properties and composition. If something feels off, it's flagged before production even starts.
Its production mainly includes trimming, drilling, tapping, and surface treatment. The quality inspection center will complete sampling and testing. The ultimate load test requires a tensile force of more than 3 times the safety factor. The following is an introduction to our production plant, surface treatment plant, and quality inspection center.
Choosing the right supplier for precast concrete inserts comes down to four key things: quality, lead time, service, and price. Miss any of them, and you're going to face problems on-site-delays, failures, or worse. At HULK Metal, we've optimized every link in the chain to deliver safer, faster, and more cost-efficient lifting & fixing sockets. Here's how we help you stay ahead with every order:
As a top metalworking service provider, we want to let every customer experience a sense of security in purchasing, sales, etc., and better realize their value through continuously defining new standards for products and services.
