Henan Worthwill Industry Co., Ltd. supplies aluminum gutter coil for manufacturers, distributors and contractors producing seamless rain gutters, downspouts and related rainwater-system components. The product is also commonly described as painted aluminum gutter coil, prepainted gutter coil, color coated aluminum gutter coil or aluminum coil for rain gutters.
Unlike general-purpose painted aluminum coil, gutter coil must be selected with the roll-forming process in mind. Aluminum alloy, temper, thickness, slit width, coating flexibility, coil inside diameter and coil winding condition can all affect feeding, bending and the appearance of the finished gutter.
Worthwill can supply gutter coil as parent coil or custom slit coil. Buyers should provide the gutter-machine feed width and finished profile before production so the coil specification can be matched to the downstream forming process.

Aluminum gutter coil is flat aluminum coil supplied in a thickness and width suitable for continuous roll forming into rain gutters and related drainage components. For painted gutter systems, the aluminum is normally coated before it is delivered to the gutter manufacturer or installer.
Prepainted aluminum allows the gutter profile to be formed from material that already has the required surface color and finish. This avoids painting each finished gutter section separately and helps maintain more consistent appearance across long continuous profiles.
The material must remain formable enough for profiling while providing sufficient stiffness for handling and installation. For this reason, gutter coil should be specified as a complete combination of alloy, temper, thickness, coating system and machine feed width rather than simply purchasing a coil by color.
3003 and 3105 are two common 3xxx-series aluminum alloys used for roll-formed building products.
3003 aluminum provides a practical combination of corrosion resistance, formability and moderate strength. It is widely used for roofing components, building products and other formed aluminum applications where reliable bending and forming are important.
3105 aluminum provides higher strength than common commercially pure aluminum grades while retaining useful forming characteristics. It is commonly selected for gutters, downpipes, siding, roofing profiles and other continuously formed architectural components.
For gutter production, the alloy should be selected together with the temper and thickness. A harder or thicker material is not automatically the correct choice for every machine. Profile depth, bend radius, required rigidity, forming speed and downstream handling should all be considered.
For additional alloy information, see our 3003 Aluminum Sheet & Coil and 3105 Aluminum Sheet & Coil pages.
In the North American gutter industry, aluminum gutter coil is commonly described using thicknesses such as .027 inch and .032 inch. These are direct thickness references rather than a true steel-style gauge system.
Worthwill's current published gutter coil range is 0.70–1.00 mm, approximately .028–.039 inch. Buyers using specifications such as .027 or .032 inch should provide the exact required thickness and tolerance so the order can be confirmed before production.
Thinner material reduces material consumption and can be easier to form, while thicker material generally provides greater rigidity. The correct selection depends on gutter profile, gutter size, local installation practice, forming equipment and project requirements.
Thickness should therefore be confirmed together with alloy and temper rather than selected independently.
Gutter coil width is determined primarily by the gutter profile and the roll-forming machine.
Common finished slit widths found in the gutter market include approximately 11.75 inch, 11.875 inch and 15 inch, depending on the gutter system and equipment. These dimensions should be treated as machine-specific references rather than universal standards.
Worthwill's current published parent gutter coil width is 610–990 mm. The parent coil can be reviewed for slitting into narrower feed coils according to the customer's gutter machine, required profile and production quantity.
When requesting custom slit gutter coil, buyers should provide the exact feed width, width tolerance, edge requirement, coil ID and preferred coil weight. This is more reliable than ordering only by a finished gutter description such as “5-inch gutter” or “6-inch gutter.”
The coating system should be selected according to the installation environment, expected exterior exposure, color requirement and project budget.
PE coated aluminum provides a broad color range, good forming performance and economical cost. It can be suitable for gutters and building components used in moderate exposure conditions when the complete coating specification is appropriate for the project.

HDP provides improved exterior durability and UV resistance compared with conventional polyester. It is a practical option for roofing, gutters, wall systems and other exterior building products where better weather performance is required without automatically moving to a PVDF system.
See our HDP Coated Aluminum Coil & Sheet page for more information.
PVDF coated aluminum is generally considered for demanding exterior applications where long-term weatherability, UV resistance and color retention are important. It can be specified for gutters used in strong sunlight, coastal environments or other demanding exterior conditions when the complete coating structure is suitable.
See our PVDF Coated Aluminum Coil & Sheet page for detailed information.

Worthwill can produce aluminum gutter coil in common RAL colors and can also match an approved physical color sample. White, gray, black, brown and other architectural colors are commonly requested for rainwater systems, but the final color range depends on the selected paint system and order requirements.
Color approval should not rely only on a computer screen or online color chart. For custom colors or projects requiring close color consistency, an approved physical coated sample provides a more reliable production reference.
Gloss level, visible side, reverse-side coating and protective-film requirements should also be confirmed before production.
Successful gutter forming depends on more than aluminum thickness.
Alloy and temper: The material needs sufficient strength for the finished gutter while remaining suitable for continuous forming and bending.
Thickness consistency: Stable thickness helps the coil feed consistently through the roll-forming machine and supports uniform finished profiles.
Slit width and edge condition: Correct feed width and clean slit edges help reduce feeding problems and dimensional variation during continuous production.
Coating flexibility: The coating system must remain compatible with the required bends and profile geometry.
Coil ID and winding: Coil inside diameter, coil weight and winding condition should match the buyer's decoiler and handling equipment.
Color consistency: For large projects or repeat orders, color, gloss and approved reference samples should be controlled between production batches.
Aluminum gutter coil is primarily supplied for continuous forming of rainwater-management products, including:
The exact coil specification should be matched to the finished profile rather than applying one standard gutter-coil specification to every application.
Typical inspection items for aluminum gutter coil include alloy and temper confirmation, aluminum thickness, coil width, slit-width tolerance, surface appearance, color, gloss, coating-film thickness, coating adhesion, forming performance, coil edge condition, coil ID, winding quality, labeling and packing.
Where a project has specific testing requirements, the applicable test method and acceptance criteria should be stated in the purchase specification. Third-party inspection can also be arranged by agreement.
For color-coated gutter coil, retaining an approved color sample is recommended when appearance consistency between production batches is important.
Worthwill can provide coil coating, slitting and recoiling according to the required gutter-coil specification. Protective film or other surface-protection methods can be discussed where the coated face requires additional protection during downstream forming, handling or transport.
Coils are packed with moisture-resistant wrapping, edge protection, strong strapping and export pallets according to coil dimensions and transport requirements.
Coil ID, coil weight, pallet orientation and loading requirements should be confirmed before production when the buyer has specific decoiling or warehouse-handling equipment.
Henan Worthwill Industry Co., Ltd. supplies aluminum sheet, coil, foil and coated aluminum products for international industrial and architectural markets. Gutter coil production can be coordinated with aluminum substrate selection, color coating, slitting and export packing according to the buyer's final forming requirements.
Worthwill's color coated aluminum production supports PE, HDP and PVDF systems, RAL colors and custom color matching. Slitting and other processing services allow gutter coil to be prepared according to the customer's downstream equipment rather than supplied only as a general-purpose painted master coil.
Sample approval, production inspection and third-party inspection by agreement can be arranged for projects that require additional specification control.
