Key points of geogrid construction
1. Construction site: it is required to compact, level and remove sharp and protruding objects. 2. Grid laying: on a flat and compacted site, the main stress direction (longitudinal) of the installed grid shall be vertical In the direction of the embankment axis, the pavement shall be flat, witho...Read more -
What are the main functions of geotextile in the inverted filter
The characteristics of the protected soil have an impact on the anti-filtration performance. The geotextile mainly acts as a catalyst in the anti-filtration layer, which promotes the formation of an overhead layer and a natural filter layer in the upstream of the geotextile. The natural filter la...Read more -
What are the reasons for the damage of hot-dip galvanized steel grating
The hot-dip galvanized steel grating will be damaged after it has been used for a long time. In order to avoid damage to the hot-dip galvanized steel grating as much as possible, the maintenance of the steel grating should be done well at ordinary times. The maintenance of outdoor hot-dip galvani...Read more -

How good is the fatigue cracking resistance of geo grid
Geogrid uses high-strength polyester fiber or polypropylene fiber as raw material, and adopts warp knitting oriented structure. The warp and weft yarns in the fabric are free of bending, and the intersection is bound with high-strength fiber filament to form a firm joint, giving full play to its ...Read more -
How to distinguish between true and false galvanization?
Galvanized steel pipe, also known as galvanized steel pipe, is divided into two types: hot-dip galvanizing and electrogalvanizing. The hot-dip galvanized coating is thick, uniform, with strong adhesion and long service life. Galvanizing cost is low, and the surface is not very smooth. Galvanized ...Read more -
