Long-Span Roofing & Acoustic Cladding for Sports Arenas and Hangars

Aviation hangars, indoor sports arenas, and grand exhibition halls feature unobstructed clear spans up to 60 meters, severe wind uplift forces, extreme indoor reverberation, and high indoor humidity that demand specialized acoustic structural envelopes.

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.

Critical Industry Risk Factors: Long-span public and aviation buildings confront three severe hurdles: First, "Acoustic Reverberation". Solid metal liners reflect up to 95% of ambient noise, transforming sports matches or live events into an unintelligible din. Second, "Extreme Wind Uplift". Giant hangar doors opening during storm fronts generate sudden internal pressure surges that attempt to peel roof panels off structural purlins. Third, "Chlorine Corrosion". In indoor swimming pools, chloramine vapor attacks standard galvanized steel, corroding roof decks within a few seasons.

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.

ROOF PANEL CONFIGURATION 5-Rib High Moment PIR / Rockwool

High moment resistance bridging purlin spans up to 2.50m with solar PV readiness.

WALL PANEL CONFIGURATION Concealed-Fix (WM) / Visible-Fix (W)

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.

Step-by-Step Site Installation Guide

1. Rafter Deflection & Level Survey: Survey 30m-60m rafter cambers and purlin alignments using laser total stations prior to hoisting.
2. Continuous Z-Purlin Lapping: Bolt S350GD high-tensile Z-purlins with continuous overlap laps over each portal rafter to establish beam continuity.
3. Acoustic Panel Placement: Hoist perforated acoustic rockwool panels with spreader beams, verifying the protective acoustic veil remains intact.
4. Dual Fastener Storm Restraint: Fasten heavy saddle washers through every high rib across perimeter eave zones to meet hangar wind uplift engineering.
5. Siphonic Gutter Integration: Seal oversized box gutters with continuous polyurethane adhesive and integrate siphonic roof drainage sumps.
