Extreme Marine Corrosion Resistant Envelopes for Shipyards and Port Facilities
Naval shipyards, dry docks, container freight stations, and marine cargo terminals face extreme coastal exposure: continuous saltwater spray (ISO 12944 C5-M), colossal wind suction pressures up to 300 kg/m² across 25-meter portal eaves, and industrial blasting grit.
- ✓ Cut-to-Length: Custom continuous lengths from 2.00m to 13.50m
- ✓ Freight Capacity: Domestic truckloads or 40ft High Cube container stuffing
- ✓ Static Support: Purlin span, wind uplift, and quantity takeoff support
- ✓ System Quality: Certified testing per European EN 14509 norms
Key Engineering Advantages for This Sector
Structural Demands & Operational Challenges
Naval shipyards, dry dock enclosures, mega-yacht assembly halls, marine freight stations, and container port logistics hubs occupy the most corrosive atmospheric environments on earth: the open marine coastline. Continuous wave aerosols and salt-laden storm winds deposit a persistent, highly conductive electrolyte film over building surfaces. Categorized under ISO 12944 as Atmospheric Corrosivity Class C5-M (Very High Marine), standard 25-micron coil coatings degrade and blister within months, zinc galvanic layers dissolve, and fastener heads shear off in high winds. Inside colossal shipbuilding halls spanning 25 to 30 meters in clear height with 100-ton overhead cranes, building envelopes must withstand abrasive grit-blasting dust internally while defying relentless gale-force coastal weather externally. SerPan Metal’s marine shipyard program delivers 200-micron Plastisol, heavy PVDF coatings, and Grade 316 A4 stainless fastening systems engineered to conquer coastal environments.
Optimized Composite Panel & Sub-Framing Systems
SerPan Metal addresses these marine extremes through a coordinated high-specification envelope: Exterior facings are coated with heavy 200-micron leathergrain Plastisol or 35-micron fluoropolymer PVDF. Plastisol creates a thick, resilient barrier that prevents airborne marine chlorides from ever reaching the steel substrate. For roof integrity, we deploy heavy 5-rib panel profiles secured with high-grade 316 A4 austenitic stainless steel fasteners fitted with EPDM vulcanized washers and crest saddle spreads to resist 320 kg/m² suction loads without tearing. Secondary structural purlins utilize heavy S350GD high-tensile Z-profiles with Z275 to Z450 gr/m² hot-dip galvanizing, continuous sleeved across portal rafter bays.
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
Coastal weatherproofing accounts for driving sea gales capable of sweeping rainwater upward along shallow pitches. Ridge caps are dimensioned 50% wider than standard and sealed with dual-tier closed-cell profile foam fillers. Longitudinal panel laps receive dual continuous beads of non-hardening, salt-resistant butyl mastic. Heavy-duty 1.50mm hot-dip galvanized or coated steel box gutters measuring up to 500x500mm handle immense storm precipitation catchment volumes.

Optimized Envelope Systems for This Application
Selected composite panels and secondary steel profiles delivering peak lifecycle performance.
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.
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.
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.
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.
Water tightness and architectural aesthetics of a metal building envelope depend directly on coordinated flashings, ridge caps, valley gutters and corrosion-resistant fasteners.
