Premium structural walk boards designed to withstand high wind load cycles, seismic movement, and rigorous CAL-OSHA Title 8 requirements across SoCal building developments.
The construction sector in Los Angeles County and Southern California operates under some of the most challenging parameters in the United States. High seismicity (governed by the California Building Code, Title 24, and ASCE 7 structural design criteria) demands scaffolding equipment with superior structural flexibility and load capacities. In addition, the marine environment surrounding the Port of Los Angeles (POLA), Port of Long Beach (POLB), and coastal regions like Santa Monica and El Segundo causes accelerated atmospheric corrosion of temporary structures.
Tianjin Minjie Steel Co., Ltd. addresses these specific regional requirements by engineering high-yield Q235B and Q345B steel walk boards and marine-grade 6061-T6 aluminum planks. By utilizing advanced pre-galvanization and hot-dip galvanization processes, our walk boards offer superior salt-fog corrosion resistance. This makes them ideal for prolonged exposure to California’s coastal humidity and marine atmospheric conditions.
For operations in California, federal OSHA compliance is not enough. The California Division of Occupational Safety and Health (Cal/OSHA) enforces stricter rules under Title 8 of the California Code of Regulations (Subchapter 4, Article 22). Key requirements include:
| Material Spec | Yield Strength (MPa) | Tensile Strength (MPa) | Typical Applications in LA | Corrosion Protection |
|---|---|---|---|---|
| Q195 Carbon Steel | ≥ 195 MPa | 315–430 MPa | Lightweight residential framing, indoor access platforms | Pre-galvanized (zinc coating 80-120 g/m²) |
| Q235B Structural Steel | ≥ 235 MPa | 370–500 MPa | Standard commercial access, masonry scaffolding systems | Pre-galvanized / Hot-dip galvanized (zinc coating >220 g/m²) |
| Q345B High-Strength Steel | ≥ 345 MPa | 470–630 MPa | Heavy shoring towers, bridge construction, heavy industrial plants | Hot-dip galvanized (ASTM A123 compliant) |
| 6061-T6 Structural Aluminum | ≥ 276 MPa | ≥ 310 MPa | High-rise facade maintenance, suspended platforms, marine environments | Natural oxide layer / Anodized finish option |
A globally recognized manufacturer of steel pipes and scaffolding products, delivering reliable materials since 1998.
Tianjin Minjie Steel Co., Ltd. was established in 1998. Our expansive manufacturing facility spans over 70,000 square meters, strategically located just 40 kilometers from XinGang Port—the largest and most active maritime hub in Northern China. This proximity enables fast shipping routes to major West Coast ports in the United States, including the Port of Los Angeles and Port of Long Beach.
We operate 4 pre-galvanized production lines, 8 ERW steel pipe lines, and 3 hot-dipped galvanized processing lines, all certified to ISO 9001 quality management standards. Our processes conform strictly to ASTM, GB, DIN, and JIS codes to ensure that safety and reliability are built into every single walk board and structural pipe we produce.
To support high-load engineering requirements, we hold multiple structural patents, including customized groove, shoulder, and victaulic piping systems. Our annual output across structural tube, hollow section, and scaffolding walk board divisions exceeds 300,000 metric tons.
Every batch of raw material undergoes rigorous chemical analysis and physical testing. From steel coil leveling and shear cutting to profile punching, cold-forming, welding, and final galvanizing, our QA inspectors monitor every stage to guarantee complete compliance with ASTM A123/A123M standards for zinc coating thickness and surface finish.
Our scaffolding systems and walking boards have been successfully utilized in industrial environments worldwide, demonstrating reliability across different climatic conditions.
Collaborations focused on corrosion-resistant access platforms for wet, high-humidity port environments, meeting stringent safety criteria.
High-volume supply of Q235 and Q345 steel walk boards for high-density metropolitan infrastructure projects, operating under heavy load cycles.
Providing heavy-duty galvanized structural scaffolding products compliant with AS/NZS codes for harsh outback mining and coastal terminals.
Providing custom-designed walking boards and structural framework matching advanced modern petrochemical and high-tech plant designs.
Supplying galvanized scaffold planks designed to withstand extreme thermal expansion and high ambient dust loads in dry refinery complexes.
Rapid shipping of durable structural steel pipes and standard scaffolding components to aid urban rebuilding programs.
We maintain rigorous testing protocols to verify structural performance before export.

Designed for commercial engineering, these walk boards feature structured anti-slip dimples, optimized thickness, and custom-sized hooks for direct integration into system scaffolds.
Ensure structural integrity of your scaffolding towers with certified hollow sections, galvanized round tubes, and structural framing elements.
As construction projects grow in height and complexity, standard structural access platforms must adapt. Tianjin Minjie Steel Co., Ltd. is leading several manufacturing initiatives aimed at improving durability and safety on site:
By optimizing punch die shapes and raising spacing configurations, our new anti-slip walking board patterns increase traction under wet, oily, or ice-prone scenarios, meeting safety requirements in varying climates.
We are integrating high-strength micro-alloyed steel (HSLA) to reduce overall plank weight by up to 15% without sacrificing load capacity. This simplifies manual handling and reduces erection fatigue on jobsites.
Our hot-dip galvanization processes utilize high-purity zinc pools with trace nickel additions. This improves coating adhesion and layer uniformity, protecting steel structures from coastal humidity and industrial atmospheres.
Essential compliance, logistics, and material information for Los Angeles and West Coast structural engineers.
Yes. Our walk boards are engineered and batch-tested to satisfy the 4:1 structural safety factors and the maximum span deflection limit of L/60 dictated by California Code of Regulations (CCR) Title 8, Section 1637. Test reports and load tables are available upon request during structural submittals.
Our manufacturing plant is located 40 kilometers from XinGang Port (Tianjin), which runs weekly freight vessels to the Port of Los Angeles (POLA) and the Port of Long Beach (POLB). Normal ocean transit times range from 18 to 25 days, with total order-to-delivery cycles generally spanning 35 to 45 days, depending on custom fabrication requirements.
Q235B is the standard carbon steel used for most access scaffolding platforms, offering a balance of ductility and strength. Q345B has a higher yield strength (345 MPa vs 235 MPa), making it suitable for high-load shoring, concrete slab support scaffolding, and structures with longer unsupported spans.
Yes. We customize width configurations (e.g., 210mm, 240mm, 250mm, 420mm, 500mm), overall span lengths up to 4 meters, hook styles matching different tube diameters (typically 42.3mm or 48.3mm scaffold tubes), and wind lock styles according to client drawings.
Our pre-galvanized walk boards utilize double-sided zinc coatings to slow rust formation. For harsh marine coastal exposures, such as port renovations in San Pedro or Long Beach, we recommend our hot-dip galvanized (HDG) steel boards, which provide a thick, alloyed zinc layer that prevents rust and corrosion.
