large construction nailsWith the increasing use of hook mesh, the method of bridge rail is also different. The height of the outer railing of the walkway or seat belt should not be lower than 1.10 meters. The net distance between railings should not be greater than 140 mm and horizontal bar rails should not be used. The planning of the hook mesh is necessary to be safe and reliable, the bolt should be installed on the basis of the railing, its strength should meet the requirements of the standard.

When producing galvanized wire, the wire is pickled. Pickling is to use some acid mist or acid to wash off some oxides on the surface of iron, that is, rust, and some other corrosive substances, to achieve the purpose of cleaning iron, so that zinc will fall off when galvanizing.

Post time: 15-08-22Galvanized wire coating rough, passivation film is not bright, bath temperature is too high. If the cathode current density is too high, zinc content in the bath is too high or sodium hydroxide and DPE content is too low; Solid particles or excessive foreign metal impurities in the electroplating solution can cause such problems. Solution: If the coating of large galvanized wire is rough, there may be solid particles in the plating solution. If the roughness of the part is severe, the current density may be too high.
For the wide use of screen, the state has regulations. You also specify the diameter size, mesh size, or usage method. For plastering mesh, mesh should be less than 20 and diameter greater than 1 nm. Not only are specifications specified, but safety is preferred if wire mesh is used in exterior plastering mesh. If you fall, the consequences are unimaginable. Therefore, the application of norms should be combined with reality.
- Hook net use value is still very high, has a very good sex, and its manufacturing concise generous, beautiful, not in high temperature will fade, you can save a sum of maintenance costs, but also according to the different needs of the site to change the shape, to meet the needs of the site.
Galvanized hexagonal mesh uses: building wall fixed, heat preservation, heat insulation; Power plant piping, boiler heating; Anti-freezing, residential protection, landscaping protection; Raise chicken and duck, isolate chicken and duck house, play the role of protecting poultry; Protect and support seawalls, hillsides, roads and Bridges and other waterworks.

For key and important parts with tensile strength greater than 1034Mpa, the stress should be removed at 200±10℃ for more than 1 hour before plating, and for carburized or surface hardened parts, the stress should be removed at 140±10℃ for more than 5 hours. The cleaning agent used for cleaning shall have no effect on the binding force of the coating and no corrosion on the substrate. Acid activation Acid activation solution should be able to remove corrosion products and oxide film (skin) on the surface of parts without excessive corrosion on the matrix.
