1, the general steel barrel outside the barrel of iron phosphate after chemical treatment, the inner surface without oil pollution impurities, high cleanliness, rust-proof ability to enhance;
2, the use of standard triple seven-ply process, so that the steel barrel has excellent impact resistance and air tightness.
3, the introduction of the W-bar technology, so that the steel barrel of the lateral impact of the strength of the increase, so that the thickness of the steel drum thin, for customers to reduce costs become possible.
4. This type of steel barrel is suitable for low corrosive chemical raw material, lubricating oil, food additive, coating and resin.
