LASER-CUT & WELDED ARCHITECTURAL SCREENS
Engineered solar interceptor matrix combining custom CNC multi-axis laser carving, seamless TIG seam fusion, and ASTM B117 salt-spray resistant Class I architectural finishes. Spec ID: ALU-GR-2000 // CSI 07 42 13.
What is the ALU-GR-2000 Screen System?
Unlike static planar louvers, the ALU-GR-2000 multi-layer Mashrabiya acts as an active visual barrier and passive thermal shield. During zenith solar noon (75°+), 4mm-depth structural ribs block 88% of thermal infrared irradiance while maintaining uninterrupted outward sightlines.

Why Choose Our Architectural Screens?
Computational microclimate engineering validation based on ASHRAE 90.1, EN 1991-1-4 boundary wind tunnel models, and solar radiation ray-tracing simulations.
−48.4% Cooling Load
Peak cooling load reduction across SW elevations under 45° solar incidence — SHGC from 0.78 unshaded to 0.24 with ALU-GR-2000.
82.3% Daylight Uniformity
Useful Daylight Illuminance (UDI 300–3000 lux) with DGP < 0.28 imperceptible direct glare cutoff.
15kW Fiber Laser Precision
Swiss Bystronic CNC fiber lasers carve burr-free chamfer contours; post-perforation thermal annealing guarantees 1.0mm flatness per 3,000mm.
Seamless Robotic TIG Fusion
Multi-axis robotic TIG seam welding with four-stage metallurgical grain blending forms monolithic rigid spatial volumes without visible fastening seams.
Adaptive Environmental Envelope Performance
Class I Architectural Finish Library
ASTM B117 salt-spray resistant Class I architectural finishes with 25-year exterior warranty — anodized, PVDF liquid, superdurable powder, and timber sublimation.
Perforation Patterns & Panel Geometry
Aperture-calibrated open area matrix from 15% to 65%. Standard parametric families below, or fully bespoke patterns machined from your CAD vector files (.DWG / .DXF / .AI).
Islamic Octagram Mashrabiya
Classical 8-point star tessellation for cultural and heritage architecture — typical open area 30–45%, engineered as interlocking unitized cassettes.
Parametric Sine Wave
Flowing amplitude-modulated ribs for contemporary commercial elevations — 15–40% porosity, wavelength tuned to mullion module spacing.
Organic Hex Density
Gradient hexagonal cell fields flowing from opaque to 65% open — ideal for parking screens and plantroom ventilation enclosures.
Concealed Subframe & Fixing Details
Precision-engineered extruded aluminum mounting cleats allow three-axis site adjustment (X, Y, Z ±15mm) while mitigating thermal expansion stresses through neoprene-isolated sliders.
Concealed Floating Bracket
Interlocking male-female 6063-T6 cleat mechanism fastened into curtain wall transoms or slab edge brackets via M10 A4-80 stainless anchors — 1.8 kN per cleat dead load, ±15mm 3-axis site adjustment.
Hinged Sub-Frame for BMU Access
Screen panels swing 95° inward or outward on internal stainless pivot hinges for glazing washing and BMU cradle access — 10,000 operational cycles, dual aircraft wire safety lanyard.
Thermal Bushing & Isolators
Dielectric PTFE shims and EPDM rubber collars isolate aluminum frames from carbon steel brackets, eliminating galvanic reaction in high-salinity marine environments — ΔT 60°C (+6.5mm) travel, ASTM D149 tested.
