APPLICATIONS

img
Railway Sleepers

PC wires are used to prestress concrete railway sleepers, significantly increasing their strength and durability. This allows them to withstand heavy loads and harsh weather conditions, making them a reliable and long-lasting solution for railway infrastructure.

img
Hume Pipes

PC wires are used to prestress concrete Hume pipes, enhancing their structural integrity and resistance to internal and external pressures. This makes them ideal for use in drainage systems, sewerage networks, and other underground infrastructure projects.

img
Prefabricated Concrete Slabs

PC wires are used to prestress concrete slabs, improving their load-bearing capacity and reducing deflection. This makes them suitable for use in various construction applications, such as flooring, roofing, and bridge decks.

img
Prefabricated Concrete Poles

PC wires are used to prestressed concrete poles, increasing their strength and resistance to bending and breaking. This makes them ideal for use in power transmission and distribution lines, as well as for street lighting and signage.

Frequently Asked Questions

Got questions? We've covered the essentials here.

The minimum order quantity for the majority of our products is 5 tons. However, for our retail segment, there is no MOQ, allowing customers to purchase products directly from our channel partners based on their specific requirements.
To ensure consistent mechanical properties in our products, we perform several key tests during both in-process testing and final inspection. These include assessing ultimate tensile strength, elongation, and meticulously measuring carbon content.
Our typical lead times for domestic orders range from 7 to 10 days, contingent on location and specific product requirements. For international orders, shipments generally take 1 to 2 months, varying with destination and product specifications.
Yes, we offer customization options for product diameters, compositions, and packaging. These services are provided based on client needs and the quantity ordered.
Our process for addressing quality discrepancies and rejections after delivery is as follows:

For domestic orders: Upon notification of an issue, we send our representatives to inspect the delivered materials and collect samples for retesting. Following this, we prepare Minutes of the Meeting (MOM) based on findings and proceed with material replacement.

For international shipments: We offer discounts or refunds for the delivered cargo, depending on the severity of the issue, size of shipment and the location.
To guarantee high quality, we source our raw materials exclusively from certified suppliers that meet industry standards. All incoming materials undergo a thorough inspection in our in-house testing laboratories to ensure adherence to these standards. Only materials that satisfy our stringent quality criteria are approved for production.
