HRB400/HRB400E Deformed Steel Rebar

HRB400 is a steel reinforcement material with high strength and good plasticity. HR stands for "hot rolling", which essentially refers to the heating and rolling process of steel bars in the production process. B represents that its yield strength is 400 megapascals (MPa) higher than that of ordinary carbon steel. HRB400 steel bars are mainly composed of alloys of carbon, sulfur, phosphorus, manganese and other elements, which have weather resistance, corrosion resistance and high tensile strength.

Product Description

HRB400/HRB400E Deformed Steel Rebar Description

1. High strength: The yield strength of HRB400 steel bars is 400 MPa, which has higher strength and tensile properties compared to general carbon steel, and can effectively increase the bearing capacity of concrete components.
2. Good plasticity: HRB400 steel bars have good toughness and elongation after being subjected to stress, and can maintain high strength even if bending and deformation occur.
3. Good welding performance: HRB400 steel bars have good weldability and can be welded with other steels, making them convenient for use in construction.
4. Weather resistance: HRB400 steel bars have good weather resistance and can be used for a long time in harsh weather conditions, making them less susceptible to oxidation and corrosion.
5. Simple construction: The shape of HRB400 steel bars is relatively simple, usually flat or circular, which is convenient for processing and use.

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.
