3105 is an aluminum-manganese alloy widely used in building products where corrosion resistance, strength and low material weight are required. H18 temper provides relatively high hardness and rigidity for suitable corrugated roofing, siding and profiled panel applications.
Because H18 is a harder temper, the required bend radius, corrugation geometry and forming method should be evaluated before production. Trial material can be used when profiles include tight bends, deep corrugations or demanding edge-forming operations.
Aluminum naturally develops a protective oxide layer, while the lacquered surface provides an additional barrier against moisture and atmospheric exposure. Coating selection can be adjusted according to coastal salt exposure, rainfall, ultraviolet radiation and the required exterior service conditions.
Aluminum provides a lightweight material option for large roof and facade areas, supporting easier coil handling, panel transportation and installation. The final gauge should be selected according to panel shape, support spacing, wind load and structural design requirements.
Prepainted coil provides a finished surface before roll-forming, allowing roofing and facade manufacturers to process coated material directly into profiles. Color, coating type and gloss can be approved before volume production for repeat project supply.
PE coating provides an economical prepainted surface for general residential, agricultural and light commercial construction. It can be selected where standard color, surface protection and exterior performance are required.
SMP coating can be considered for projects requiring improved exterior durability compared with conventional polyester systems. The final formulation should be selected according to UV exposure, rainfall, color requirement and expected service conditions.
Optional heat-reflective PVDF coating can be specified where stronger UV resistance, exterior color retention and reduced solar heat absorption at the coated surface are important project considerations.
Heat-reflective performance varies with coating formulation, pigment and color. Buyers requiring a specific solar or infrared reflectance value should provide the required test method and acceptance criteria before coating approval.
Custom widths from 800 mm to 1250 mm allow roofing manufacturers to match incoming coil dimensions to their corrugating and roll-forming equipment. Selecting the correct feed width can reduce unnecessary trimming and improve material utilization during continuous panel production.
Buyers can provide the required feed width, finished panel coverage, profile drawing, corrugation dimensions and forming-machine information. The production width and tolerance can then be confirmed before the order is released.
The coil can be processed using suitable equipment for corrugating, profiling, slitting, bending and crimping. For demanding profiles, testing the proposed H18 temper, coating type and gauge on the customer's actual production line is recommended before large-volume supply.
3105 H18 lacquered aluminum coil can be used as incoming material for suitable corrugated and profiled roof panels used on homes, workshops, warehouses, agricultural buildings and commercial facilities.
The coil can also be formed into facade siding and exterior wall profiles where lightweight construction, corrosion resistance and consistent color are required. Roof and wall materials can be produced in coordinated color specifications.
Applications include residential roofing, farm buildings, agricultural sheds, storage structures, workshops and exterior wall panels where lightweight prepainted material is preferred.
Custom-width coil can support continuous production of roof and wall panels for warehouses, distribution buildings, industrial sheds and prefabricated structures requiring larger quantities of consistent material.
Potential applications include maintenance buildings, workshops, storage facilities, site offices and other project structures. Gauge and coating selection should be confirmed according to the actual site environment and engineering requirements.
Standard RAL colors and custom-matched shades are available. For repeat project orders, an approved color sample or color standard should be retained as the reference for subsequent production batches.
Gloss and surface appearance can be discussed according to the coating system and architectural requirements. Buyers should confirm color and finish before mass production when roof and facade panels need a coordinated appearance.
Protective film can be discussed where the coated surface requires additional protection during slitting, roll-forming, handling, transport or installation. Film type and peel strength should be matched to the downstream process.
Production can be inspected according to the agreed alloy, temper, dimensions, coating system, color and project requirements. Inspection items can be defined before production for distributor, OEM and project orders.
