As the economic engine of East Java and Indonesia’s second-largest metropolis, Surabaya represents a pivotal nexus for maritime trade, shipbuilding, chemical refining, and mega-infrastructure development. The rapid expansion of the Tanjung Perak Port area, combined with intensive industrial activity across the Rungkut Industrial Estate (SIER) and the Gresik Industrial District, has dramatically escalated the demand for high-specification, certified scaffolding walk boards and structural steel access systems.
Operating in a tropical maritime environment entails extreme engineering challenges. Scaffold platforms deployed near the Madura Strait are continuously exposed to saline atmospheric humidity, high ambient temperatures, and heavy seasonal monsoon downpours. Conventional timber decking or poorly galvanized steel planks suffer rapid structural degradation, posing severe fall hazards and operational downtime.
To address these localized challenges, international EPC contractors and tier-1 Indonesian builders are shifting toward advanced Q235/Q345 hot-dip galvanized (HDG) steel walk boards and structural aluminum catwalks engineered with self-draining anti-slip perforations and heavy-duty load distribution ribs.
Direct maritime freight route optimized for fast sea transportation from Tianjin Xingang terminal.
Certified manufacturing rigor ensuring zero-defect load distribution across all steel walk boards.
Understanding the mechanical properties of scaffold walk boards is essential for structural safety engineers overseeing projects in East Java. The table below outlines standard performance metrics for structural scaffolding walk boards supplied to the Surabaya industrial market:

Tropical precipitation in Surabaya can create acute slip hazards on smooth steel plates. Our engineered walk boards feature perforated dimple patterns with raised matrix crowns that provide superior coefficient of friction (COF > 0.75) while permitting rapid water drainage.
To eliminate center flex and torsional deflection under heavy worker traffic or equipment staging, the underside of each plank is reinforced with continuous stiffener ribs, achieving minimal deflection (< L/240) under peak working loads.
Forged heavy-duty hooks are robotically welded to the plank ends, ensuring seamless coupling with standard 48.3mm scaffold tubes, Ringlock systems, or Cuplock ledgers across complex construction setups.

Spanning an expansive facility of over 70,000 square meters, the factory is strategically situated just 40 kilometers from XinGang Port—the largest shipping hub in Northern China—enabling rapid maritime logistics directly to Surabaya’s Tanjung Perak Port.
Minjie Steel operates a sophisticated industrial infrastructure comprising:
All operations strictly conform to international standards including GB, ASTM, DIN, and JIS. The enterprise maintains comprehensive ISO 9001 Quality Management Certification, ensuring full traceability from raw steel coil selection to final loading.
Tianjin Minjie Steel Co., Ltd has established an extensive global sales network. Supported by first-class technical advisors and experienced engineering personnel, Minjie’s products are exported to over 60 countries across Southeast Asia, the Middle East, Australasia, and Europe.
In September 2019, senior engineers visited key clients in Singapore, solidifying long-term supply frameworks for marine-grade scaffolding walk boards used in Singapore's offshore dockyards.
In 2019, Korean industrial partners visited Minjie facilities with custom walk board structural designs, resulting in streamlined manufacturing of heavy-duty hooked metal planks.

Surabaya’s coastal maritime environment exhibits elevated atmospheric salinity and humidity. Pre-galvanized steel planks typically have a thinner zinc layer (120-220 g/m²) and raw cut edges. Hot-dip galvanizing after punching coats the entire structural plank—including internal edges and drainage holes—with a heavy 450-600 g/m² (≥ 65 μm) zinc-iron alloy coating, preventing rust formation and ensuring a service life exceeding 15–20 years in coastal East Java.
The standard widths for scaffold planks supplied to Indonesian sites are 210mm, 225mm, 240mm, 250mm, and 500mm (catwalks), with lengths ranging from 1.0m to 4.0m. Under BS EN 12811-1 standards, our heavy-duty Q235B walk boards are rated for Load Class 4 (3.0 kN/m²) through Load Class 6 (6.0 kN/m²), fully satisfying safety protocols enforced by Indonesian Ministry of Manpower (Kemenaker).
