ARCHITECTURAL STEEL WALL PANELS
High-tensile structural steel cassettes engineered for extreme wind loads, severe public transit impact resistance, and maximum span flatness exceeding traditional aluminum thresholds. Spec ID: ALU-ST-7000 // ISO 9001 / EN 13501 A1.
What is Series ALU-ST-7000?
Heavy-duty architectural cladding for railway concourses, civic institutions and coastal high-rise crowns — where impact resilience, fire integrity and multi-storey span flatness exceed what aluminum can deliver. Cassette depth 40–120mm, single panels up to 8,000mm continuous.
Substrate Alloy Grade
HDG Z275 hot-dip galvanized steel / COR-TEN A/B weathering steel / AISI 316L marine stainless.
Sheet Thickness
1.5 / 2.0 / 2.5 / 3.0mm (approx. 23.5 kg/m² at 3.0mm gauge).
Surface Finishing
3-coat PVDF 35µm (PPG Duranar, 25-yr) / super-durable powder Qualicoat Class 2 / PVD ceramic sputter titanium bronze & gold / stabilized Cor-Ten patina sealer.
Engineered Scope
Rail & metro concourses, civic institutions, coastal headquarters, cultural pavilions.
Certified Performance & Deflection Metrics
Independently tested under ASTM and European EN façade standards (CNAS / UKAS accredited lab). ALUMAX steel cassettes deliver 300% greater impact resilience than standard architectural aluminum cladding.
210 GPa Modulus of Elasticity
Three times the rigidity of standard aluminum (70 GPa), permitting ultra-wide uninterrupted module spans with zero oil-canning — ASTM A653 / EN 10346.
Class IV Hard Body Impact
Surpasses 10 Joules steel sphere drop without permanent cosmetic indentation — mandatory for railway and subway concourses (EN 14019 / ASTM E695).
5.5 kPa Design Wind Pressure
Tested to L/300 deflection limit under cyclic hurricane wind pressure — suited for coastal high-rise crown installations (ASTM E330 / CWCT Class 1).
5,000 Hrs Salt Spray Endurance
Zero blistering or creep with hot-dip Z275 + epoxy barrier + PVDF topcoat — C5-M extreme marine corrosion resistance (ISO 9227 / AAMA 2605).
Structural Data Schedule
Architectural Tone & Finish Library
PPG Duranar 3-coat PVDF, super-durable Qualicoat Class 2 powder, PVD ceramic sputtered titanium finishes, and stabilized Cor-Ten patina — RAL / NCS custom color match available.
Robotic Bending & 15kW Fiber Laser Centers
Millimeter-level dimensional repeatability enabled by advanced European automated sheet-metal centers — 450,000 m² annual structural facade capacity.
Salvagnini P4 Automated Panel Bender
Universal bending tools fold complex upward/downward positive and negative bends automatically without tool changes — ±0.25mm corner fold tolerance with uniform tight radii.
Trumpf 15kW Solid-State Fiber Laser
Nitrogen high-pressure burr-free cutting on up to 8mm heavy-gauge stainless and weathering steel plates, including intricate bespoke perforated patterns.
6-Axis Robotic Seam Welder
Automated continuous corner laser welding prevents thermal distortion, followed by robotic planar micro-grinding for seamless 90° razor corners.
Engineered Mounting Substructures
Three proprietary load-bearing fixing systems accommodate high dead loads, dynamic seismic inter-story drift, and thermal movement without visible exterior fasteners.
Heavy-Duty Hook-On Rainscreen
Continuous top hook receiver tabs with integral EPDM isolators — rapid progressive installation and singular panel demountability for maintenance. Joint 15–20mm open rainscreen, ±25mm seismic drift capacity.
Flush Secret-Fix Stud Anchor
Capacitor-discharge welded M8 stainless rear studs eliminate heat tint and face print-through — a monolithic, screw-free glass-flat facade with 10mm tight hairline joints. Stud pull-out load ≥ 8.2 kN per stud.
Seismic Inter-Story Expansion
Floor-to-floor deflection relief channels for supertall buildings, mitigating concrete slab creep and major seismic tier displacement. Joint movement horizontal ±50mm / vertical ±35mm — AAMA 501.4 / 501.6 compliant.
