Highly durable, certified, and corrosion-resistant walk boards designed to withstand structural loads and harsh Midwest meteorological conditions.
The construction sector of Chicago, Illinois—from high-rises in the Loop to industrial expansions in Elgin, Naperville, and Joliet—is governed by stringent safety norms and structural requirements. Due to the high wind shear forces originating from Lake Michigan, walk boards and scaffold components must be engineered to withstand exceptional horizontal load distributions and uplift pressures. Wood planks often degrade under high humidity and freeze-thaw cycles. Therefore, regional safety managers increasingly demand high-strength galvanized steel and lightweight aluminum walk boards.
Furthermore, Chicago’s local building codes and OSHA Region V regulations require temporary work platforms to provide a guaranteed 4:1 safety factor. This demands rigorous mechanical testing for deflection and material structural integrity. Our range of pre-galvanized and hot-dip galvanized walking boards is designed to handle local load classifications, providing reliable stability during skyscraper restoration, bridge maintenance, and industrial refinery upgrades.
Founded in 1998, Tianjin Minjie Steel Co., Ltd. has established itself as an industry leader in steel tube and scaffolding fabrication. Our production base spans over 70,000 square meters, strategically positioned just 40 kilometers from XinGang Port (Tianjin), the largest port terminal in Northern China. This logistical location ensures rapid shipping and efficient supply chains for bulk walk board orders destined for North America and Chicago port entries.
Equipped with 4 pre-galvanized production lines, 8 ERW steel pipe lines, and 3 hot-dip galvanized processing lines, we maintain an annual output exceeding 300,000 tons. Our manufacturing processes conform strictly to international standards, including ASTM, GB, DIN, and JIS. Additionally, we hold ISO 9001 quality certifications and have secured three national design patents for specialized piping structures: groove, shoulder, and victaulic connections.
Through our rigorous raw material sourcing and quality control checks, we ensure that every scaffold walk board exported to the US provides high structural strength, reliable welding parameters, and durable anti-corrosion protection.
Our products are exported worldwide, supporting industrial and civil infrastructure projects across Asia, Europe, the Americas, and Oceania.
We regularly participate in the Canton Fair and send engineering teams to support client installations worldwide. For example, our Australian partners regularly audit our manufacturing facilities to ensure our structural steel and scaffolding planks consistently meet local safety standards. Similarly, our clients in Singapore, South Korea, India, and Lebanon trust us for regular, large-volume shipments of high-strength structural tubing and safety walking planks.

Our development roadmap focuses on optimizing structural strength while reducing weight. This table details our material properties, designed to meet the demands of demanding industrial environments.
| Steel Grade / Material | Yield Strength (MPa) | Tensile Strength (MPa) | Zinc Coating Options | Ideal Application Scenario |
|---|---|---|---|---|
| Q195 Carbon Steel | ≥ 195 MPa | 315 - 430 MPa | Pre-Galvanized (120g/m²) | Lightweight facade scaffolding, interior masonry platforms. |
| Q235 / Q235B Steel | ≥ 235 MPa | 370 - 500 MPa | Pre-Galv (150-200g/m²) / Hot-Dip Galv (≥ 400g/m²) | Standard construction walk boards, framing, general building platforms. |
| Q345B High-Tensile Steel | ≥ 345 MPa | 470 - 630 MPa | Hot-Dip Galvanized (≥ 500g/m²) | Heavy industrial refineries, infrastructure, and heavy-duty bridge staging. |
| Structural Aluminum (6061-T6) | ≥ 276 MPa | ≥ 310 MPa | Anodized Anti-Oxidative Finish | High-rise suspended platforms, lightweight modular scaffolding. |
To address safety concerns during Chicago's winter sleet and snow, our design engineers developed a slip-resistant surface pattern. By utilizing computerized CNC punching, we create raised, dimpled perforations that offer slip resistance in all directions while allowing water and snow to drain freely. This design feature reduces build-up on the platform, mitigating structural overload risks and improving safety under foot.
In addition to walk boards, we manufacture a comprehensive selection of galvanized tubes, pipes, and high-tensile wire products to support complete construction assemblies.
For operations in Chicago, safety compliance is a critical requirement. Our walk boards are engineered to align with OSHA Standard 1926 Subpart L (Scaffolds) guidelines, which govern factors such as maximum load capacity, deflection limits, and safety margins. Every product undergoes testing to verify it meets these load requirements.
