Special Facade Works
Bespoke architectural engineering for landmark building envelopes. We specialize in non-standard structural steel outriggers, high-transparency cable truss atriums, complex geometrical skylights, and monumental entrance facades requiring rigorous 3D spatial modeling, finite element analysis (FEA), and certified high-altitude rigging.
Monumental Architectural Canopies
Engineered large-span cantilevered and tie-rod suspended entrance canopies constructed with structural steel hollow sections (SHS/RHS) and clad with solid metal, FR composite cassettes, or point-supported structural glass. Designed with rigorous wind uplift calculations and integrated drainage to shelter building drop-offs and grand reception portals.
- Finite Element Analysis (FEA) checking live gust wind uplift, dead loads, and cantilever deflection limits.
- Grade 316 marine stainless steel tension tie-rods and CNC-machined clevis fork-end connectors.
- Concealed perimeter drainage gutters with integrated heat tracing and high-volume internal downspouts.
- Weatherproof soffit cladding with seamless integration of architectural LED downlighting channels.
Architectural Skylight Systems
Complex roof-glazing envelopes engineered in pyramid, hipped, barrel-vault, segmented dome, and free-form polygonal geometries. Fabricated with custom heavy-duty extruded aluminium rafter profiles with multi-tier internal condensation troughs that harvest daylight while completely sealing against torrential rain and heat buildup.
- High-performance double-glazed units (DGU) with ceramic frit patterns for glare control and solar heat reduction.
- Continuous secondary internal condensation guttering draining moisture harmlessly outside the roof curb.
- SentryGlas (SGP) laminated safety inner glass preventing catastrophic overhead fallout upon impact.
- Structural rafter spans engineered to withstand maintenance walk-on loads and localized wind vortices.
Multi-Story Atrium Glazing
Grand, highly transparent vertical envelopes engineered for central lobbies, hotel atriums, and convention center gathering spaces. Supported structurally by full-height laminated glass fins or prestressed horizontal stainless steel cable trusses, delivering soaring multi-story sightlines without heavy opaque structural columns.
- Multi-ply toughened laminated glass fins engineered as continuous structural vertical mullions.
- Pre-tensioned stainless steel cable nets maintaining structural equilibrium under dynamic wind suction.
- Heavy-duty sliding top spring boxes absorbing building live-load deflections and thermal expansion.
- Non-corrosive investment cast SS 316 spider brackets and articulated routel assemblies.
Feature & Dynamic Facades
Complex 3D parametric facade envelopes incorporating perforated metal kinetic screens, twisted architectural fins, curved panoramic corner glazing, and integrated media facade lighting. Tailored for landmark projects where the building skin serves as a sculptural brand icon and an active environmental shade filter.
- BIM 3D parametric modeling ensuring clash-free coordinate delivery between steel, glass, and MEP services.
- CNC laser-perforated aluminium panels with custom perforation ratios for optimized solar shading.
- Cold-bent and cylindrical curved laminated glass manufactured to strict optical reflection tolerances.
- Concealed maintenance walkways, cat-tracks, and facade access cradle tracks engineered directly into the system.
Monumental Entrance Facades
Signature main entrance elevations integrating oversized revolving doors, double-height curtain walls, composite portal framing, and thermal air-lock vestibules. Engineered to handle high pedestrian traffic while presenting an imposing corporate identity and minimizing air-conditioning thermal loss across lobby thresholds.
- Engineered structural steel portal frame skeletons clad in premium solid aluminium or composite plate.
- Seamless integration with high-capacity 3-wing or 4-wing automatic revolving glass doors.
- Thermal air-curtain pockets and vestibule draught-lobbies reducing HVAC energy expenditure.
- Flush threshold details compliant with universal accessibility and barrier-free building codes.
Architectural Glass Features & Skywalks
Specialized structural glass installations including glass pedestrian skybridges, cantilevered glass viewing cubes, scenic capsule elevator glass shafts, and illuminated architectural glass sculptures. Constructed with multi-ply laminated tempered safety glass that acts as primary load-bearing structural elements.
- Triple and quadruple laminated glass panels incorporating high-strength SentryGlas (SGP) structural interlayers.
- Slip-resistant ceramic frit patterns and acid-etched treads applied to structural glass flooring planks.
- Redundant load-path structural design guaranteeing full barrier containment even if multiple plies fracture.
- Custom stainless steel clamp brackets with POM isolation gaskets preventing localized stress risers.
