Steel Scaffold
Galvanised steel scaffolds are manufactured from S355J2 structural hollow sections with minimum yield strength of 355 MPa and tensile strength of 490–630 MPa. All tubes are hot-dip galvanised to BS EN ISO 1461 with zinc coating thickness of 55–85 μm, providing 25-year corrosion protection in Singapore's Category C4 atmospheric environment. Steel systems achieve load classifications from Class 1 through Class 6 under BS EN 12811-1.

Galvanised steel scaffold systems from Ezzogenics deliver tensile strength exceeding 400 MPa, heavy-duty load ratings to 6.0 kN/m², and 25-year service life in tropical marine environments.
Galvanised Steel Scaffold Components
Ezzogenics' steel inventory is manufactured from S355J2 structural hollow sections with minimum yield strength of 355 MPa and tensile strength of 490–630 MPa. All tubes are hot-dip galvanised to BS EN ISO 1461 with zinc coating thickness of 55–85 μm, providing corrosion protection for 25+ years in Singapore's Category C4 atmospheric environment. The component range includes standard 48.3 mm OD × 3.2 mm WT tubes, 48.3 mm OD × 4.0 mm WT heavy-duty tubes, pressed-steel swivel and right-angle couplers rated at 6.25 kN slip resistance, base jacks with 150 mm × 150 mm base plates and 600 mm threaded adjustment, and U-head jacks with 4.5 mm wall-thickness U-channels.
Cross-bracing assemblies utilise 20 mm × 3 mm flat steel with M16 turnbuckle adjustment for racking stiffness. Transoms are fabricated from 48.3 mm × 3.2 mm tube with welded end fittings for drop-forged coupler engagement. Decking options include BS 2482 Grade A timber planks (38 mm × 225 mm, 1.5 kN/m² uniformly distributed load), steel planks with anti-slip embossing rated at 3.0 kN/m², and aluminium-plank hybrids for weight-sensitive applications.
Structural Performance and Load Ratings
Steel scaffold systems achieve load classifications under BS EN 12811-1 ranging from Class 1 (0.75 kN/m²) through Class 6 (6.0 kN/m²). Ezzogenics' heavy-duty configurations utilise 4.0 mm wall-thickness standards at 2.0-metre lift heights with plan-bracing at every fourth bay, achieving Class 5 and Class 6 ratings for masonry facade work, concrete formwork support, and industrial tank cladding.
The elastic modulus of steel (200 GPa) provides minimal deflection under load, maintaining platform serviceability limits of span/200 for general access and span/300 for formwork support. Steel's fatigue resistance under cyclic loading — critical for wind-exposed facade scaffolds — exceeds that of aluminium by a factor of three. For projects involving dynamic loading from material hoists or personnel lift gates, steel systems are specified exclusively by Ezzogenics' engineering team.
Corrosion Protection and Lifecycle Economics
Hot-dip galvanising provides sacrificial corrosion protection: the zinc layer corrodes preferentially, protecting the underlying steel even at coating breaches. In Singapore's coastal environment with chloride deposition rates of 80–150 mg/m²/day, Ezzogenics' galvanised components exhibit first maintenance corrosion after 15–20 years. For high-salinity sites within 500 metres of the coast, supplementary organic topcoats (epoxy-polyurethane systems) extend protection to 25+ years.
Steel systems are economically justified for project durations exceeding 18 months or where systems will be redeployed across multiple projects. Capital cost is recovered at the 24-month rental equivalent mark. Ezzogenics provides depreciation schedules and residual-value assessments for capital procurement decisions, alongside full rental options with inclusive maintenance and inspection services.
Applications and System Integration
Steel scaffolds are mandatory for formwork support, heavy-duty shoring, and facade retention where loads exceed 3.0 kN/m². Ezzogenics integrates steel systems with proprietary H-frame configurations, cuplock modular nodes, and tube-and-fitting bespoke layouts. Steel tubes are reusable across project cycles: end preparation (cutting, notching, welding) does not compromise galvanised protection if zinc-rich repair paint is applied to cut surfaces.
For high-rise applications, steel facade scaffolds are tied to the structure at vertical intervals not exceeding 4.0 metres and horizontal intervals not exceeding 6.0 metres per BS EN 12811-1. Ezzogenics' design team calculates tie loads for each structural substrate — RC walls, steel frame nodes, or curtain-wall mullions — ensuring that anchorage forces do not exceed substrate capacity. All steel system designs are issued with Professional Engineer endorsement for BCA submission.

Scaffolding Materials
Material selection determines scaffold load capacity, service life, and regulatory compliance. Ezzogenics supplies BS EN-certified steel, aluminium, timber, and bamboo with traceable test certificates.
Scaffolding FAQ
The optimal scaffold system depends on height, load demand, geometry, and duration. Our engineering team evaluates these parameters and recommends frame, tubular, suspended, tower, or mobile configurations with PE-endorsed design drawings.
Every scaffold exceeding 4 metres requires PE design approval, MOM-certified erectors, and handover inspection. We manage all regulatory requirements including BCA submission and weekly competent-person inspections.
MOM mandates weekly inspections by a competent person. Re-inspection is required after weather events, structural alterations, or impacts. We provide weekly inspection services with photographic documentation.
Yes. All non-standard scaffolds, systems exceeding 30 metres, and cantilevered configurations receive PE-endorsed structural calculations, load-path verification, and BCA submission documentation.
Steel offers higher load capacity (up to 6.0 kN/m²) for heavy-duty construction. Aluminium provides 50–60% weight reduction for faster assembly and manual handling, ideal for interior fit-out and maintenance.
