一、怎祥选择镀锌钢管塑料大棚? 镀锌钢管装配式塑料大棚从80年在我国问世以来,由于它外形美观、装拆方便、透光性好、节约钢材等优点,几年来发展很快,目前全国已有了3千多亩的钢管塑料大棚。镀锌钢管大棚的优劣,关键是镀锌。镀锌方法有两种。一种是电镀,另一种是热浸镀锌。电镀锌表面光滑、美观,但镀层薄,在潮湿环境下易生锈,寿命短。而经过热浸镀锌的钢管,不但镀锌层厚,而且锌的附着力强,其寿命大约10～15年,是保护地设施中一种比较理想的防锈措施。目前我国采用热浸镀锌的
First, how to choose galvanized steel pipe plastic greenhouse? Galvanized steel pipe assembly plastic greenhouse from 80 years since its launch in the country, because of its beautiful appearance, easy assembly and disassembly, good light transmission, saving steel and other advantages, the rapid development in recent years At present, the country has more than 3,000 acres of steel plastic shed. The pros and cons of galvanized steel pipe greenhouse, the key is galvanized. There are two ways to galvanize. One is electroplating, the other is hot-dip galvanized. Galvanized steel surface is smooth, beautiful, but the coating is thin, easy to rust in the humid environment, short life. The hot-dip galvanized steel pipe, not only galvanized layer thickness, and strong zinc adhesion, and its life expectancy of about 10 to 15 years, is a protective facilities in the ideal anti-rust measures. At present, our country uses hot dip galvanized
