Rockshield Mesh is an essential component in the construction and protection of pipelines, particularly in environments where geological movements and backfilling can pose significant risks. This article delves into the materials typically used to manufacture Rockshield Mesh, its properties, installation methods, pricing, and suppliers, along with frequently asked questions.

Materials Used in Manufacturing Rockshield Mesh

High-Density Polyethylene (HDPE)

The primary material used in the production of Rockshield Mesh is high-density polyethylene (HDPE). This thermoplastic polymer is favored for several reasons:

• Durability: HDPE is known for its strength and resistance to impact, making it ideal for protecting pipelines from damage caused by rocks and other abrasive materials during backfilling.
• Chemical Resistance: The chemical inertness of HDPE ensures that it does not degrade or rot over time, even when exposed to harsh environmental conditions.
• Flexibility: HDPE's flexibility allows it to conform to various shapes and sizes of pipelines, facilitating easier Rockshield Mesh installation in challenging environments.

Mesh Structure

Rockshield Mesh features a diamond-shaped open mesh structure that enhances its protective capabilities. This design allows for:

• Water Flow: The open structure permits water to flow through without compromising the cathodic protection systems essential for preventing corrosion.
• Impact Absorption: The mesh's design helps distribute impacts from external forces, thereby reducing the risk of damage to the pipeline coating.

Thickness and Weight

Typically, Rockshield Mesh comes in various thicknesses, with common specifications including:

• Thickness: Ranges from 6 mm to 11 mm.
• Weight: Approximately 1700 g per square meter for thicker variants.

These specifications contribute to its overall effectiveness in protecting buried pipelines.

Properties of Rockshield Mesh

Rockshield Mesh is engineered to meet specific performance criteria:

• Temperature Resistance: Capable of withstanding temperatures between -30°C and +100°C (-22°F to +212°F), making it suitable for diverse climatic conditions.
• Impact Resistance: With an impact resistance rating of 17 Joules, it provides robust protection against physical impacts.
• Compressive Strength: Exhibits compressive strength exceeding 600 KPa at 50% deformation, ensuring it can withstand substantial loads without failing.

Installation of Rockshield Mesh

Installation Methods

Installing Rockshield Mesh involves wrapping the mesh around the pipeline and securing it with strapping bands. There are several methods for installation:

1. Longitudinal Wrapping: The mesh is wrapped along the length of the pipeline.
2. Latitudinal Wrapping: The mesh is wrapped around the pipeline's circumference.
3. Spiral Wrapping: The mesh is applied in a spiral manner for enhanced coverage.

These methods ensure complete protection against geological hazards and backfilling impacts.

Ease of Installation

One of the standout features of Rockshield Mesh is its user-friendly installation process. Its lightweight nature and flexibility allow for quick handling and application, even in difficult terrains.

Pricing and Suppliers

Rockshield Mesh Price

The Rockshield Mesh Price can vary based on factors such as thickness, roll size, and supplier. Generally, prices range from $0.50 to $2.00 per square meter depending on these variables. For specific pricing details, it is advisable to consult suppliers directly or check online marketplaces.

Rockshield Mesh Suppliers

Several Rockshield Mesh Suppliers companies specialize in the production and supply of Rockshield Mesh. Notable suppliers include:
