Deformed Bar Steel Rebar

Deformed bar reinforcing steel bar is one kind of reinforcing steel bar. Commonly, its surface has ribs which has three kinds of shape: spiral shape, herringbone shape and crescent shape. Deformed reinforcing steel bar with high strength can be directly used in the reinforced concrete structure and also can be used as prestressed reinforcing bar after cold drawing. Because of its great flexibility, it is widely used in many fields as construction material.

    Rebar---The core skeleton of construction engineering

    Deformed bar (steel rebar) is a general term for hot-rolled ribbed steel bars with longitudinal and transverse ribs (threads) on the surface. These raised ribs are not decorative, but their core function is to form a strong mechanical bite force with concrete, significantly improving the bond strength between the steel bar and concrete, so that the two work together and bear the load together. Without it, modern high-rise buildings, large bridges, water conservancy hubs and other reinforced concrete structures would be impossible. As the core of building structural materials, its importance is self-evident.

    Why choose our rebar?


    rebar
    Strict quality

    We strictly implement international standards, and all products are certified by authoritative third-party testing agencies.

    Mainly promote HRB400E, HRB500E high-strength earthquake-resistant steel bar, which have higher yield strength, tensile strength and excellent earthquake resistance, providing key safety guarantees for buildings under extreme loads such as earthquakes.

    Precise control of chemical composition (C, Si, Mn, P, S, etc.), stable and reliable mechanical properties, uniform metallographic structure, and eliminate "slimming steel bars" from the source.

    Complete specifications

    Wide diameter coverage: From the commonly used Φ6mm, Φ8mm, Φ10mm, Φ12mm, Φ14mm, Φ16mm, Φ18mm, Φ20mm, Φ22mm, Φ25mm, to the large-size Φ28mm, Φ32mm, Φ36mm, Φ40mm, etc., to meet the needs of different parts such as beams, plates, columns, foundations, etc.

    Flexible length options: Provide standard fixed lengths (such as 9m, 12m) or customize cutting according to your engineering needs to reduce waste and reduce costs.
    Transparent and highly competitive prices

    Direct supply from the manufacturer, eliminating the middle link, providing you with truly competitive wholesale prices for rebar.

    Daily tracking of steel market prices, transparent and timely quotations, helping you to accurately control procurement costs.

    For engineering projects, long-term cooperative customers, and large-volume purchases, we provide better discount policies and flexible settlement methods.

    How to correctly choose high-quality rebar?

    1. Clarify the needs and identify the grade: According to the requirements of the design drawings, determine the grade (such as HRB400E or HRB500E must be used), specifications (diameter), length and quantity of the required steel bars. Earthquake-resistant steel bars with "E" must be used in earthquake-resistant design areas.

    2. Check the logo and trace the source: Regular rebars are rolled with clear and continuous brand marks (such as 4E, 5E), manufacturer codes (or trademarks), and specifications (diameter in millimeters). This is the key to product quality traceability.

    3. Check the warranty: Require the supplier to provide a valid material certificate (quality certificate) to check whether the furnace batch number, implementation standards, various mechanical properties and chemical composition test results are qualified and consistent with the physical mark.

    4. Appearance inspection: Observe whether the surface of the steel bar is smooth, the longitudinal and transverse ribs should be clear, full, uniform and continuous, without obvious defects such as cracks, scars, folds, and oil stains. The color should be uniform and dark blue-gray or gray-black.

    5. Choose reliable suppliers: Give priority to regular steel traders like Lishengda Company, which have stable steel plant resources, large spot warehouses, perfect quality control systems, and good market reputation. Be wary of products with abnormally low prices.

    6. Sampling re-inspection (essential for important projects): For major engineering projects or occasions with higher quality requirements, on-site sampling should be carried out according to the specifications and sent to qualified third-party testing agencies for mechanical properties (tensile, bending) re-inspection. This is the last line of defense to ensure the quality of the project.
