Product Description
Our 3004 and 3105 roofing aluminum sheet is a dedicated building envelope material engineered for roof panels, flashing, gutters, fascia and ventilation components that must survive decades of rain, snow, UV radiation and thermal cycling. Both alloys belong to the aluminum-manganese family, which gives the sheet roughly twenty percent higher strength than pure 1100 grade while keeping the excellent corrosion resistance and formability that architectural fabricators rely on every day. Every coil is rolled to tight thickness tolerance on modern mills, then inspected and packed in our workshop before shipment, so contractors receive flat, consistent sheets that run smoothly through roll forming lines and brake presses.
Compared with galvanized steel, roofing aluminum sheet weighs about sixty percent less per square meter of the same gauge, which reduces dead load on roof structures and cuts transport cost. The natural oxide film that forms on the aluminum surface heals itself when scratched, so cut edges and drilled holes remain protected without any touch-up painting. For coastal projects or industrial atmospheres where ordinary steel quickly shows rust, this alloy family delivers dependable long service life with minimal maintenance. We supply both flat sheets and master coils, with slitting, cutting to length and PE film protection available to match your production requirements.
Key Features- Superior corrosion resistance: the manganese alloyed matrix resists atmospheric attack and is widely specified for seacoast roofing where salt spray is a constant challenge.
- Lightweight structural economy: at only 2.73 g per cubic centimeter the sheet cuts roof dead load and makes site handling faster and safer for installation crews.
- Excellent roll forming behavior: H24 and H26 tempers deliver stable springback so trapezoidal and standing seam profiles hold their geometry precisely.
- Long lasting mill finish surface: the uniform bright surface accepts paint, anodizing and stucco embossing, giving designers freedom without extra priming cost.
- High reflectivity for energy saving: bare aluminum reflects a large share of solar radiation, helping reduce attic heat gain in warm climate buildings.
- Custom dimension supply: thickness from 0.4mm to 1.5mm, width up to 1500mm, and any sheet length can be produced to your cutting list.

Roofing aluminum sheet in 3004 and 3105 alloys is the material of choice for standing seam roof panels, corrugated roofing sheets, eaves flashing, valley flashings, drip edges, gutters, downspouts, copings and ventilation louvres on residential, commercial and industrial buildings. The same sheet is used by caravan and prefab house manufacturers for exterior cladding, by sign makers for weather resistant fascia, and by HVAC contractors for insulated duct cladding. Because the alloy can be roll formed, press braked and riveted without cracking, fabricators use it for almost any non-structural architectural component exposed to weather.
Packaging & Quality AssuranceEach bundle of roofing aluminum sheet is interleaved with protective film or paper, placed on a fumigation-free wooden pallet, and secured with steel strips and waterproof wrapping for ocean and air freight. Coils are wound on steel cores with edge protection and vertical or horizontal packing as requested. Our quality system covers chemical composition verification, mechanical property testing and surface inspection on every production batch, with mill test certificates and inspection reports supplied together with the goods. We welcome third party inspection before shipment and offer free samples for your roll forming trial before you place a bulk order.
