Bar grating panels and perforated panels fabricated in sizes are popularly used as louver gratings for shade screening and air flow. Bar gratings for louvres are welded pressed grating constructed with transverse bars (louvers) pressed or lock into the bearing bars at an angle between 30 and 45. Qindelin louvre gratings work as shielding screen, ventilation grilles, facade cladding panels, fencings to stop people from peering through on bridges, gangways, elevated walkways,and other sites. It has four different louver blade angles. Varying degrees of shading and ventilating effects are achieved by angle changing of the cross bars pressed in, 15°, 30° or 45°. It is made of aluminum, stainless steel or carbon steel bright galvanized.

Water well screen pipe for Dewatering Dewatering screen pipe Water removal on construction sites is often required before excavation can begin. This process is carried out to diver water away from the soil where the building foundation will be placed, keeping the area dry and solid. Xinlu’s water well screens are widely used on drainage pipes in construction sites to filter out sand from the water, and improve the water removal efficiency. Features 1. High Open Area More than 25% of open area allows water to seep through the dewatering screen at a reduce speed, while allowing for a lower flow resistance. The enhances the water removal rate, resulting in a more efficient water removal process. 2. Non-clogging Performance Continuous slots widen inwardly from the screen surface to minimize the chance of sand clogging the slot opening, 3. Excellent Pressure Resistance The wedge wire screen pipe is welded in a single from with no weld seams on the surface. Precise welding technology gives the screen its strength, making it ideal from high pressure applications 4. Great Sand Barrier Precisely machined slots keep sand, silt and clay from entering the well, preventing abrasion. 5. Easy Installation Compared to bridge slot screens or cement pipes, the wedge wire well screen in lightweight and easy to lay on the ground. It is also safe and convenient. 6. Material The screen is available is galvanized, low-carbon steel, or stainless steel in grades 304 and 316, Premium materials do not retain sand and other impurities, ensuring a non-clogging performance.
