Import Aluminum Coil For Gutters — Buy in wholesale FOB from Supplier in China

This aluminum gutter coil is manufactured from 3105-H24 alloy, a non-heat-treatable aluminum-manganese grade that offers natural corrosion resistance and good formability for continuous gutter profile forming. The material is supplied as painted coil in continuous lengths suitable for feeding into roll-forming machines to produce 5-inch or 6-inch K-type gutters, the standard residential and light commercial profiles in North American and export markets. The source indicates availability in over 30 colours, with a unique two-sided painting process that applies different colours to each face of the coil, reducing inventory holding costs for distributors who stock multiple shades.

The 3105-H24 temper provides a stable yield strength level after strain-hardening and partial annealing, giving sufficient rigidity for gutter spans while allowing clean bends at corners and end caps without cracking. Typical industry mechanical properties for 3105-H24 include tensile strength around 215-275 MPa and yield strength of approximately 145-195 MPa, though the supplier does not list specific test values in the source data. The painted finish is described as preventing dirt adhesion, flaking, and fading; typical gutter coil paint systems use polyester or fluoropolymer coatings over a chromate or chrome-free conversion coating, with dry film thickness usually ranging from 18 to 25 micrometres per side depending on colour and warranty level.

Primary buyers include gutter installation contractors, building supply wholesalers, and distributors serving the residential renovation and new construction markets. The coil format enables on-site custom gutter lengths, reducing seams and leak points compared to sectional systems. Shipment from Foshan, Guangdong Province, places production in southern China's metal processing corridor with access to Shenzhen or Guangzhou port facilities. Buyers should confirm actual minimum order quantities, available coil widths compatible with their gutter machine throat, and whether colour matching to specific RAL or proprietary shades is supported beyond the standard palette.

Litong Aluminum Industry (wuxi) Co., Ltd. lists its address at No. 9 Chengy不负责e Road, Daliang Street, Shunde, Foshan, Guangdong Province, China, postal code 528300. The supplier carries a harbor trust tier with a response rate of 0.00 percent and zero average response hours recorded. No verification badges, transaction history, or third-party audit data is present in the available profile, so buyers should independently assess production capability and quality management before reliance on this source for project-critical supply.

The company presents itself as operating paint lines for K-type and specialist gutter coils, with a stated focus on colour consistency and environmental compliance in coating operations. The product line targets contractor-supply and wholesale distribution channels rather than direct consumer sales. Buyers should verify whether the supplier owns continuous coil coating lines or outsources painting, what substrate pretreatment is employed for paint adhesion and corrosion resistance, and whether the facility holds ISO 9001 or environmental management certifications relevant to coated metal export. The Wuxi naming in the company title versus the Foshan address should be clarified, as it may indicate historical or operational links between locations.
