New 3000 Series Prepainted Aluminium Roofing Coil | China

New ZHAOYANG 3000 Series Prepainted Aluminium Coil for Roofing Sheet

Overview

This new ZHAOYANG prepainted coil is offered in the 3000 series alloys 3003, 3004 and 3105, for roll forming into roofing sheet. Paint is roller-applied and oven-baked to a stated thickness of 15 to 18 µm for polyester and 25 to 28 µm for double-coat polyester or PVDF. The coil comes from 0.2 to 1.5 mm (0.008 to 0.059 in) thick and 300 to 1500 mm wide. The minimum order is 3 tonnes, and the coil comes from Jinan, China.

Applications

The coil is made for roofing lines producing corrugated, trapezoidal and standing seam sheet, plus the matching gutters, flashings and canopies. 3000 series alloys add manganese, which makes them stronger than pure 1000 series aluminium. They are a common choice for roof sheet that has to span and take foot traffic. The supplier also lists rolling shutter and garage doors, ceilings, and composite and honeycomb panels. It suits roofing manufacturers and roll forming contractors.

Condition and seller notes

This is new mill-painted coil. The supplier says the coil cuts and forms without distortion, and that the paint holds its gloss and resists salt, acid, alkali and rain. It quotes coating warranties of 10 years for polyester and more than 20 years for PVDF, but gives no warranty terms and doesn’t say whether the paint thicknesses apply to the top face only or include the back coat. Buyers should confirm the top and back coat build, the primer, a colour card and written warranty terms before ordering.

FAQs

How thick is the paint?
The supplier states 15 to 18 µm for standard polyester, and 25 to 28 µm for double-coat polyester or PVDF. Check whether these figures are for the top face only, and ask for the back coat thickness.

Why choose a 3000 series alloy for roofing?
3003, 3004 and 3105 contain manganese, which makes them stronger than pure 1000 series aluminium while still forming well. This makes them a standard choice for roll-formed roof and wall sheet.

Which coating should I choose for a roof?
PVDF holds its colour and gloss longest outdoors, and the supplier quotes more than 20 years for it. Polyester is lower-cost and quoted at 10 years. Double-coat polyester sits between the two, with a thicker paint film.

What is the minimum order?
The minimum order is 3 tonnes (3,000 kg). Coil can be supplied in widths from 300 to 1500 mm to suit your roll former.
