The 5-1/2″ x 1-1/2″ White Vinyl Fence Ribbed Rails are white vinyl (PVC) ribbed fence rails. They play an important connecting and supporting role in fence systems such as the 6ft Flat Top 3 Rails Semi Privacy Vinyl Fence PVC Panels, and the 6ft 5 Top Semi Privacy Vinyl Fence PVC Panels. They are a durable, low-maintenance, and aesthetically pleasing fence component suitable for various applications.
Our fence rails are made of vinyl (PVC) material. Vinyl is a synthetic plastic material with many advantages. It is corrosion-resistant and can withstand various harsh weather conditions and chemical attacks. Even with long-term exposure to the outdoors, it is not prone to rust, rot, or insect infestation, thus ensuring a long service life.
The rail cross-section dimensions are 5-1/2″ x 1-1/2″, and the length can be custom-cut as needed. The vertical height of the rail is 5-1/2″, and the width is 1-1/2″. This size is relatively common and provides good strength and visual appeal. The wider design provides more stable support in the fence structure, enhancing the overall sturdiness of the fence. The rails feature a ribbed design. The ribs not only enhance the aesthetics of the rails, giving them a more three-dimensional and layered look, but the hollow spaces can also accommodate H-steel or Aluminum C Inserts to improve their bending and deformation resistance.
Due to their lightweight material and standardized dimensions, the installation process is relatively simple. They can generally be quickly assembled using dedicated connectors and tools, making installation easy even for users without professional installation experience.

PVC resin and various additives are uniformly mixed in a high-efficiency mixer according to precise formula ratios. This process is crucial and directly affects the quality of the final product.
The mixed PVC granules or powder are fed into an extruder. Under heating and rotation, the molten PVC material is extruded through a die and immediately cooled. The cooled PVC profile is then pulled out at a constant speed by a traction machine, thus controlling the size and thickness of the profile.
Once the continuously extruded PVC profile reaches the set length, an automatic cutting machine automatically cuts the profile into the required fence components, such as posts, crossbars, and slats. The cut components undergo quality inspection to check for smooth cut surfaces, burrs, cracks, and other defects.
Clean all parts of the cut and milled PVC fence to remove dust, oil, debris, and other impurities. Cleaning can be done by water washing, solvent cleaning, or ultrasonic cleaning to ensure a clean surface.
Conduct a thorough quality inspection on each product to ensure customers receive only the highest quality products. This step includes checking each assembled fence for defects and ensuring all components are securely connected and meet established standards.
Pack the qualified PVC post components according to customer requirements, typically using packing straps, plastic film, or wooden pallets for securing and protection to prevent damage during transportation.
