 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...

Features of truss

  From the perspective of material layout (or distribution), the truss can be regarded as a latticed beam as a whole, and its overall mechanical performance is similar to that of the beam. In the detail structure, each rod is used to re-direct the force flow (the nodes between the rods are not overlapped, and the bending moment cannot be transferred), and the overall layout is basically consistent with the main stress trace. Each rod is a secondary force rod, which is only subjected to tension and compression Truss, especially space pipe truss, is often made into arch. However, at this time, the arch is not a pure pressure arch, and the whole arch is still dominated by bending. We can also consider it as a curved beam in a certain sense. Of course, arch camber can increase the span capacity, and the role of "axial force" in the "beam" can not be ignored at this time, but in most cases, especially when the rise-span ratio is small, the bending is still the main part.

BOLT BALL

 BOLT BALL Space frame structure is a kind of structure connected by the node of bolt ball , so the bolt ball is the key component of the structure. In GB standard. the bolt ball is made of 45# steel with the diameter of 100mm to 300mm. Normally there are 3-12 holes in the bolt ball and each axial line of the bolt hole is through the center of the ball.
