Heavy-Duty Rebar Stakes | High-Grade Deformed Steel Bars
Product Overview
Our rebar stakes are engineered for demanding construction projects, crafted from HRB400 and HRB500-grade deformed steel bars. These stakes deliver exceptional tensile strength, seismic resistance, and longevity, making them ideal for foundations, bridges, retaining walls, and industrial slabs. Certified to ASTM A615, BS4449, and ISO 15630-1 standards, they ensure compliance with global structural integrity requirements.
Technical Specifications
| Parameter | Details |
|---|---|
| Diameter | 10mm, 12mm (±0.3mm tolerance) |
| Length | 3m, 6m, 9m, or custom-cut (up to 12m) |
| Material Grade | HRB400 (415 MPa yield strength), HRB500 (500 MPa yield strength) |
| Surface | Hot-rolled deformed ribs for superior concrete bonding (rib height: 1.0–1.5mm) |
| Hardness (HV) | 200–250 HV (Vickers hardness) |
| Coating | Optional epoxy/zinc coating for corrosion resistance in coastal or chemical environments. |
Mechanical Properties
-
Tensile Strength:
- HRB400: Minimum 520 MPa ultimate tensile strength, ensuring structural stability in high-rise buildings.
- HRB500: Up to 625 MPa, optimized for seismic zones and heavy-load applications like bridge piers.
-
Bending Strength:
- Withstands 180° cold bending without cracking (mandrel diameter = 4x rebar diameter). Perfect for curved concrete forms and helical foundations.
Identification & Marking
- Rolled Markings: Each rebar stake is embossed with the manufacturer’s logo, grade (e.g., HRB500), and diameter (e.g., 12mm).
- Color Coding: Epoxy-coated bars use color bands (blue for HRB400, red for HRB500) for quick onsite identification.
Weight Calculation Formula
Weight per meter (kg/m) = , where = diameter (mm).
Example: A 12mm rebar stake weighs . A 6m bar totals .
Why Does Steel Rust?
Even high-grade steel can corrode under specific conditions:
- Exposure to Chlorides: Coastal air or de-icing salts accelerate oxidation, leading to pitting.
- Carbonation: CO₂ penetrates concrete, lowering pH and destabilizing the protective oxide layer.
- Poor Coatings: Substandard epoxy/zinc layers fail to isolate steel from moisture and oxygen.
Manufacturing Process
| Step | Description |
|---|---|
| Hot Rolling | Billets heated to 1200°C and rolled into deformed bars with transverse ribs. |
| Quenching & Tempering | Rapid cooling and reheating to optimize grain structure for HRB500’s 500 MPa yield strength. |
| Surface Treatment | Ribs are pressed to 1.2mm depth for 30% stronger concrete adhesion vs. smooth bars. |
| Coating (Optional) | Electrostatic epoxy spray (250–300 microns) or hot-dip galvanizing (Z60–Z275 coating). |
Applications
- Foundations: Reinforce footings and pile caps in high-rises.
- Bridges: HRB500 bars resist dynamic loads and vibration in bridge decks.
- Retaining Walls: 12mm stakes provide lateral strength in soil-heavy environments.
- Precast Concrete: Ribbed surface ensures bond strength in prefab slabs and columns.
