YX 38-310
The YX-38-310 is a corrugated profiled galvalume prepainted steel panel designed for vertical and horizontal wall cladding applications on industrial structures. With a wave height of 38mm and effective coverage width of 310mm, this profile features a sinusoidal corrugation pattern that provides architectural visual texture while maintaining structural rigidity for wall girt spacing up to 1.2m. Panels are roll-formed from 500mm wide coils, producing a continuous wave pattern suitable for both exterior facade and interior liner applications in commercial and industrial buildings.

The base metal uses 55% aluminum-zinc alloy coated steel (galvalume) produced according to ASTM A792/A792M standard. The 55% Al-Zn coating provides enhanced corrosion resistance compared to pure zinc coatings in atmospheric exposure, particularly in industrial and marine environments. The coating composition consists of approximately 55% aluminum, 43.5% zinc, and 1.5% silicon by weight. AZ100 coating (100g/m² total both sides) is standard for wall cladding applications.
The exterior finish uses a polyester coating system applied over a chromate-free pretreatment. The primer layer (5μm) provides corrosion resistance and adhesion, while the topcoat (18-22μm) provides UV resistance and color retention. A service coat (5-7μm) on the reverse side provides abrasion resistance during installation and transportation. Standard RAL colors are available with matte or semi-gloss finish options.
The 38mm corrugation height provides sufficient section modulus for typical wall wind loads. For 0.6mm thickness with 12.45 cm³/m section modulus, the panel supports 1.0kN/m² wind pressure at 1.0m girt spacing with deflection within L/150 limit for cladding components. The 0.7mm gauge is specified for building eave zones, corners, and regions with basic wind speeds exceeding 130km/h.
The corrugated profile allows for longitudinal thermal movement without panel buckling. When installed horizontally, panels should be installed with the overlap facing away from prevailing weather direction. Vertical installations require a minimum 50mm end lap, while horizontal installations require one corrugation side lap with sealant tape for weather tightness.
Panels are fastened through the valley of the corrugation using self-drilling screws with EPDM sealing washers for vertical applications, or through crests for horizontal installations. Fastener spacing is 300mm on center at girts for standard conditions. For wall areas within 2m of grade, fastener spacing is reduced to 200mm to resist impact damage. Hidden fastener systems are available for projects requiring fastener-free exterior appearance.
This corrugated profile is commonly used for exterior wall cladding on manufacturing plants, warehouses, sports facilities, and agricultural structures. It also functions as interior wall liner panels in pre-engineered metal buildings, providing a durable interior surface that resists impact and abrasion from industrial operations. The 310mm narrow coverage width allows installation around building penetrations and curved surfaces with radius greater than 12m. Installation productivity ranges from 50-70m² per worker per day on standard wall elevations.
Manufacturing follows ISO 9001:2015 quality management systems. Incoming coils are tested for coating thickness, mechanical properties, and color consistency before production. Roll forming operations include in-line dimensional checks every 30 panels to verify corrugation height, coverage width, and profile alignment. Finished panels undergo visual inspection and coating adhesion testing using cross-hatch method before packaging. Material test reports are provided with each shipment.
Minimum order quantity is 300m² for standard colors; custom color matching requires 2000m² minimum. Standard production lead time is 10-15 working days after order confirmation. Panels are packed in wooden crates with interleaving paper to prevent surface abrasion during transport, suitable for both domestic trucking and international ocean shipping. Each package includes matching fasteners and color-matched touch-up sealant.
Yes, the YX-38-310 profile is suitable for both vertical and horizontal installation. Horizontal installations require sealant tape in side laps and fasteners placed through corrugation crests.
Galvalume (55% Al-Zn) provides approximately 2-4 times longer service life than equivalent weight galvanized coating in atmospheric corrosion environments, making it suitable for wall cladding where long-term appearance retention is required.
Yes, the profile can be installed over continuous insulation or with through-fastened insulation supports, and works with all common fiberglass blanket and rigid foam insulation systems used in metal building construction.
