 Corrosion Protection Process for Steel Structures Corrosion protection processes for steel structures are essential for ensuring that steel structures remain in good condition over the long term. This article provides a detailed overview of the various steps involved in these processes, including surface preparation, priming, coating application, quality control, and final inspection and acceptance. Surface treatment Surface preparation is the first step in the corrosion protection process. Its primary purpose is to remove dirt, grease, rust, and other contaminants from the surface of steel structures to improve coating adhesion and corrosion protection. Surface preparation includes the following steps: Cleaning: Removing grease, dirt, and dust from the surface of steel structures using solvents or detergents. Degreasing: Removing grease and wax-like substances with an alkaline degreaser to improve coating adhesion. Rust Removal: Removing rust and other corrosion products from the...

When gazing upon grand stadiums , airport terminals, or exhibition centers, we are often awestruck by their vast spaces. Behind such large-span structures lies a nearly universal choice—steel construction. This is no coincidence, but stems from steel's unparalleled engineering advantages. stadium High Strength, Lightweight: Pushing Boundaries Beyond Limits The core advantage of steel lies in its perfect blend of exceptional strength and lightweight properties. Compared to concrete, steel boasts an outstanding strength-to-weight ratio. This means that for buildings requiring vast column-free spaces, steel structures can achieve greater spans with smaller member cross-sections, significantly reducing the building's self-weight. Consequently, foundation requirements are lowered, enabling the ultimate liberation of space in a cost-effective manner. Exceptional Performance, Conquering Complex Challenges Steel's outstanding toughness and ductility enable it to better withstand dy...

What is the new technology for removing rust from steel structures and equipment? Rust removal 1 、 Rust removal and corrosion prevention Rust removal is the main focus, equivalent to the highest standard of GB8923 Sa2.5/St3 Grade, as the base layer of paint, can significantly extend the corrosion prevention cycle of paint. 2、Paint compatibility It can be matched with any paint without wrinkling. For example: various anti-rust paints, epoxy  zinc-rich paint, epoxy iron paint, chlorosulphonated polyethylene paint, fireproof paint, atomic  ash, etc. 3、Bonding power The anti-rust layer formed after rust removal has a microscopic reticulated structure, which is easy for paint molecules to  penetration and macroscopic roughness, which makes the resin bite strong and combines well with the steel substrate and paint. The strength is very good. 4、Safety The product is a thick yellow water-based liquid, non-toxic and non-flammable. It only works with rust. No chemical reaction wit...
