1100 H14 Prepainted Aluminium Coil

1100 H14 prepainted aluminium coil is what you get when a 1100 substrate, 99.0% pure or better, is rolled to a half-hard H14 temper and run through our colour coating line. The grade works because of how the metal behaves on its own. Pure aluminium resists corrosion without alloying elements to fall back on, and it stays ductile enough to stamp, punch and fold into panels, flashings and profiles without cracking. The H14 temper is the other half of the story. It adds just enough stiffness that a formed part holds its shape in storage, in transit and on site, so the sheet never gets so soft that it dents, sags or creeps under its own weight. That balance is why 1100 H14 prepainted aluminium coil keeps turning up in signage, roofing, lighting and appliance trim. And because the coating is cured at the mill, a 1100 H14 prepainted aluminium coil arrives ready to cut and form, which takes a whole painting step off your production line.

 Architectural decoration：Door and window frames, ceilings, curtain walls, edges and other decorative structural parts

 Light industrial products：Daily necessities shells, simple storage containers, small hardware accessories

 Electronics/light industry：Small heat sinks, electrical appliance shells, simple equipment guards

 General field：Simple chemical/food processing auxiliary accessories with requirements for corrosion resistance and lightweigh

What makes our 1100 H14 prepainted aluminium coil stand out is how evenly it balances performance and cost. It covers most everyday jobs across signage, trims, roofing and light fabrication without the price tag of a specialty material.

Conductivity that earns its keep. The high-purity 1100 base carries heat and electricity well, so the coil shows up in heat dissipation parts and small electrical components where those properties matter. It also resists corrosion from atmospheric moisture and mild chemicals on its own, which is enough for indoor use and lightly exposed outdoor spots without extra protection or alloying trade-offs.

A temper that works with you. The medium-hard H14 state cuts, bends and stamps cleanly into small parts, decorative trims and simple hardware, with no annealing or complex pre-treatment before forming. That matters on a busy shop floor, where you want to take the coil from the skid straight to the machine. The factory-applied coating holds through those steps, so colour does not peel or crack at the bend lines, and you skip a whole post-painting stage.

Coating options that stay practical. PE polyester suits indoor jobs on a budget, SMP silicone-modified polyester covers mild outdoor exposure, and PVDF fluorocarbon handles projects that need to survive years of weather. The rest of the spec stays the same, so you adjust durability and price without redesigning anything.

Scrap that comes back around. 1100 aluminium recycles at rates above 90%, so offcuts and rejects go back into the loop instead of going to waste. For a business that runs coil week after week, that adds up. It keeps long-term costs lower and gives the operation a cleaner sustainability story without extra effort.

• We attach great importance to product packaging to guarantee intact delivery of goods to customers. For standard packaging, waterproof kraft paper is used as the inner layer to avoid moisture damage during transit. Steel strips are then applied to secure the coiled materials against shifting in transportation, followed by loading onto sturdy wooden pallets to maintain overall stability. For long-distance sea freight orders, an extra layer of anti-rust film is wrapped to further shield products from moisture and salt spray corrosion in marine air.

• Customers worldwide may select either Qingdao Port or Tianjin Port as the loading port based on proximity to their destination to cut international logistics expenses and shorten transit lead time. Our team manages customs clearance and shipping arrangements throughout the whole process to streamline clients' international trade procedures.

• For delivery lead time, standard bulk orders usually take 20 to 35 days after we receive your deposit, depending on the order quantity,to help you get your products faster.
• Our minimum order quantity is usually one container, but as we mentioned before, we can negotiate the minimum order quantity for trial orders with new customers.

• We have ISO 9001 quality management system certification, which ensures our production process meets international quality standards. Our products also have CE certification, SGS and BV test reports, to prove they meet the European Union's safety and environmental standards. For products used in food contact applications, we also have FDA certification, to ensure they are safe for direct contact with food and drinking water. We also comply with international environmental protection regulations, so you don't have to worry about any compliance issues when importing our products.
• Beyond the product quality, we also offer comprehensive support services to make your purchasing experience smooth and worry-free.
• Our professional technical team is available 24/7 to answer any technical questions you have.
• With an annual output of 200,000 tons of aluminum products, we have stable supply capacity to meet your large bulk order needs, even during peak seasons. We also offer flexible payment terms, including T/T and L/C, to fit your cash flow requirements. We also provide real-time logistics tracking, so you can check the status of your order at any time, and our after-sales team will respond to any issues within 24 hours to solve them for you quickly.
