Product Description

Prestressed Steel Strand

● Steel Wire for Prestressed Concrete:
The product is mainly used to produce prestressed concrete components of various structural shapes using various tensioning techniques. In the construction of large-scale railways, highway bridges, roof trusses, crane beams, industrial and civil prefabricated panels, wall panels, prestressed concrete TV towers, nuclear power plants, and other engineering projects. Produce two surface forms: smooth and spiral ribs. American standards ASTMA416, ASTMA421, British standard BS5896, Japanese standard JISG3536, international standard ISO6934, European standard EN10138

● Steel Strand for Prestressed Concrete :
This product is mainly used for reinforcing prestressed concrete structures. Such as large-span railway and highway bridges, crane beams, geotechnical anchoring engineering, multi-layer industrial factories, coal mines, sports venues, etc. Main executive standard: ASTM A416

● Unbonded Steel Strand for Prestressed Concrete:
Post tensioned unbonded prestressed steel strands are used for cast-in-place floor slabs, prefabricated beams with large loads, and other specially designed structures in large-span and large-span buildings. It has the characteristics of no need for reserved holes, no need for grouting, simple construction, material saving, and easy bending.

FAQ

Q1: What metal materials do you supply?

Jiangsu Zhongersheng is a professional manufacturer mainly supplying carbon steel, hot-dip galvanized steel, PPGI color coated steel, 201/304/316 stainless steel sheets, coils, tubes and profiles, as well as various steel structural parts. Our products serve infrastructure, photovoltaic, machinery manufacturing, chemical and new energy industries.

Q2: Can you customize material grades, thickness and sizes?

Full customization is available. For carbon steel, galvanized steel and stainless steel, thickness, width and length can be adjusted in accordance with ASTM & EN standards. Profiles can be cut and processed as per drawings, and special steel materials can be customized via production line scheduling.

Q3: What’s the difference between galvanized steel and color coated PPGI?

Hot-dip galvanized steel features pure zinc anti-rust coating with cost-effective and wear-resistant performance, suitable for steel brackets, guardrails and load-bearing structures, and supports secondary painting. PPGI takes galvanized sheet as base material with colorful coating for anti-rust & decorative purposes, widely used for factory roof/wall panels and energy storage housings. Thick galvanized steel is recommended for rainy coastal areas, while PPGI is ideal for decorative outdoor projects.

Q4: Do you have spot inventory? What’s your MOQ?

We built a 10,000-ton standardized warehouse with abundant spot stock of carbon steel, galvanized steel and stainless steel. MOQ is 1 ton for standard sizes; small samples of dozens of kilograms are acceptable. No upper limit for bulk engineering orders, mixed container loading of multiple steel types is supported.

Q5: How long is the delivery time for spot goods & customized goods?

Spot goods can be loaded within 3-7 days; simple cutting & bending processing orders take 7-10 days; mould opening & special steel customization takes 15-30 days, subject to specific specifications confirmation.
