long-term durability: in the suburban environment, the standard hot-dip galvanizing anti-rust thickness can be maintained for more than 50 years

1. The cost of treatment is low.
2, long-term durability: in the suburban environment, the standard hot-dip galvanizing anti-rust thickness can be maintained for more than 50 years without repair; in urban or offshore areas, the standard hot-dip galvanized anti-rust coating can be maintained for 20 years without repair; 3. Good reliability: the galvanized coating is metallurgically combined with steel and becomes a part of the steel surface, so the durability of the coating is more reliable.
4, the toughness of the coating is strong: the galvanized layer forms a special metallurgical structure, which can withstand mechanical damage during transportation and use; 5, overall protection: every part of the plated parts can be galvanized, even in depressions, sharp corners and hidden places cable tray elbow supplierbe fully protected; 6, time-saving and labor-saving: galvanizing process is faster than other coating construction methods, and can avoid the time required for brushing on the site after installation.
The expansion joint of hot-dip galvanized bridge is a structural joint set along the appropriate part of the direction of the construction joint of the building or structure in order to prevent the building members from cracking or destroying the structure due to the change of climate temperature. so what is the treatment method of cable bridge expansion joint?
Method 1. At least one side of the bridge to cross the expansion joint has a long straight line segment, which should be more than 30m, or the straight line segments on both sides of the expansion joint add up to 30m, and there is no horizontal or vertical bend in the middle.
In order to leave the expansion margin of the cable (or wire) in the bridge tray, this margin should be greater than the expansion joint width L.
Method 2. When there is enough space under the bridge at the expansion joint, the bridge can be disconnected, and the disconnection distance B should be greater than the building expansion joint width L, and it is necessary to ensure that all cables can stretch freely with the expansion joint without being damaged, and at the same time meet the requirements of the minimum bending radius R of cable.
Method 3. If there is not enough space under the bridge at the expansion joint, the specification of widening straight-through and widening straight-through should be set closer to the expansion joint, and enough cable expansion margin should be left (greater than L). At the same time, the expansion can meet the needs of the minimum bending radius of the cable.
The distance B between the two sides of the expansion joint can be slightly larger than the width of the expansion joint L.
When there is no horizontal space at the expansion joint and the widening straight-through cannot be installed, it can be shifted appropriately to both sides of the expansion joint.
When one wide straight-through on cable tray elbow supplierside still can not meet the requirements of the expansion amount and the minimum bending radius of the remaining cable, two symmetrically connected wide straight-through can be installed on both sides of the expansion joint.
The distance between the bridges on both sides of the expansion joint B is still slightly greater than L.
