Key Engineering Advantages for This Sector
Structural Demands & Operational Challenges
Aircraft hangars, indoor sports arenas, aquatic centers, and expansive exhibition halls push the boundaries of structural engineering. These facilities feature column-free clear spans from 30 to over 60 meters. Huge roof catchment planes situated on exposed airfield perimeters face immense aerodynamic wind suction forces during severe storms. Concurrently, cheering crowds and referee whistles inside sports arenas generate intolerable indoor reverberation and echoing unless acoustic mitigation is designed. Furthermore, indoor aquatic centers evaporate chlorine gases that corrode metal envelopes from within. SerPan Metal manufactures engineered perforated acoustic rockwool sandwich panels, heavy-duty continuous Z-purlin systems, and C4/C5 chlorine-resistant coatings for grand long-span envelopes.
Optimized Composite Panel & Sub-Framing Systems
SerPan Metal addresses indoor reverberation by engineering acoustic rockwool sandwich panels (SP-ROOF-ROCK Acoustic) featuring factory-perforated interior steel facings backed by non-woven acoustic tissue. Sound waves pass through the perforations directly into the 100 kg/m³ rockwool core, achieving a certified Noise Reduction Coefficient of NRC = 0.85 to absorb echoes. For aviation hangars, we specify 5-rib panels with heavy 0.60mm outer skins anchored to heavy S350GD Z250/Z300 purlins with reinforced dual-fastener schedules. In aquatic centers, panels receive a 50-micron high-build polyurethane/polyamide coating providing total chemical resistance against airborne chlorine and constant humidity.
High moment resistance bridging purlin spans up to 2.50m with solar PV readiness.
Airtight tongue-and-groove joint profile with micro-rib surface planarity.
Thermal Envelope, Fire Safety & Energy Performance
Thermal gains and losses through the building envelope represent up to 40% of an industrial facility’s annual operating energy expenditures. SerPan Metal polyisocyanurate (PIR) cores deliver an ultra-low thermal conductivity of λ = 0.022 W/mK, while non-combustible rockwool cores deliver certified fire barriers resisting temperatures above 1000°C for 60 to 120 minutes (REI 60–120).
Weatherproofing & Drainage Engineering
Watertightness across broad arched or low-pitch hangar roofs relies on continuous single-span panels up to 13.50 meters paired with engineered thermal expansion joints. Mega-door parapets and eave cantilevers incorporate dual-hemmed storm flashings engineered to stop wind-driven rain from back-surging beneath trims. High-capacity siphonic drainage outlets are secured with heavy-duty EPDM compression flanges.

Optimized Envelope Systems for This Application
Selected composite panels and secondary steel profiles delivering peak lifecycle performance.
Rock wool panels feature high-density mineral wool fibers positioned perpendicular to metal faces. Engineered for high-risk industrial facilities, transformer rooms and sound-insulated enclosures.
PIR foam offers enhanced cross-linked molecular bonds that char upon exposure to heat, suppressing flame spread while maintaining peak thermal insulation. Flame-retardant PIR core paired with high-moment 5-rib crown geometry makes it the premier insurance-approved choice for rooftop solar PV installations.
Concealed-fix panels hide all fasteners within the joint tongue, creating clean architectural shadow lines, uniform facades and preventing water ingress at screw points.
Cold-formed C and Z purlins replace heavy hot-rolled steel sections, reducing structural weight by up to 40% while accelerating bolting speed with factory-punched holes.
CNC-bent box gutters and custom flashings ensure complete rainwater collection, storm drainage and clean structural transitions for large roofs and facades.
Manufactured from 1200 mm steel coils to provide a full 1000 mm effective cover width with 6 ribs. Fewer end-laps, faster installation, and maximum area coverage per panel make it the industrial benchmark for factory roofs and warehouse walls.
