The surface quality of the transformer aluminum strip
It is required be flat and smooth, neat and the corners are rounded after the chamfering process.
It has no defects such as roll marks, black lines, bright spots, scratches, bumps, etc.
The aluminum strip has no oil spots, tearing, blistering, etc. formed after annealing.
As an experienced transformer aluminium strip manufacturer facing to the global market, we pay attention to the packaging to ensure the quality during the transportation. We have two kinds of packaging: large roll packaging and wooden box packaging.
Large roll packaging: The size of the large roll is determined according to the width, thickness, roll diameter and length customized by the customer.
Wooden box packaging: The size of the wooden box is determined by the length, thickness, width and single box weight customized by the customer.
