1. Lightweight, high-strength, and easy to install

• Fiberglass pallets have a low density and weigh only about one-quarter as much as steel pallets of the same size (for Φ125, weight is just 0.38kg).
• Easily installed by a single person, significantly reducing physical strain for underground workers and boosting support construction efficiency.
• The product delivers exceptional compressive and shear strength. By optimizing the resin formulation and fiberglass layout, the pallet achieves superior load-bearing and shear resistance, with shear strength ≥ 75 MPa and total anchorage force exceeding 130 kN.
• Stable and reliable performance; resists cracking or perforation under anchor pretension force and surrounding rock deformation pressure, ensuring overall system stability.
• Achieves perfect strength matching with fiberglass anchor rods

2. Flame-retardant and anti-static, intrinsically safe for underground use

• Meets strict mining safety standards with excellent flame retardant and anti-static properties.
• Anti-static resistance value shall not exceed 3×10⁸ Ω; non-combustible and does not generate static sparks.
• Completely eliminates the risk of sparks from metal trays rubbing or striking underground.
• Completely eliminate risks of gas and dust explosions underground, fully meeting coal mine explosion-proof safety entry requirements.
• Ideal choice for high-gas mines and high-risk work environments

3. Corrosion and rust resistant for long-lasting durability

• FRP composites naturally feature corrosion resistance, moisture resistance, and rust prevention.
• Resistant to underground water, acidic and alkaline mineral water, and humid air corrosion; remains rust-free and non-degrading over long-term use.
• Ensures long-term, stable operation in harsh tunnel environments such as damp or water-exposed areas.
• Lasts far longer than traditional steel pallets, significantly reducing maintenance and replacement costs while eliminating the hassle of ongoing upkeep.

4. Non-conductive insulation for safer construction

• Excellent overall electrical insulation; non-conductive and non-current-transmitting.
• Effectively prevents underground leakage and electric shock accidents
• Adapted for intelligent mining and electrified roadway construction scenarios

5. Easy to cut, spark-free, and designed for dynamic construction.

• During underground rectification or roadway withdrawal, support plates can be directly cut. The cutting process is spark-free, low-temperature, safe, compliant, and requires no special protective measures.
• Especially at fully mechanized mining faces and in ribs requiring direct cutting by the shearer, using fiberglass trays with fiberglass bolts eliminates safety hazards and equipment wear caused by cutting metal.
• Adapts to dynamic mining construction requirements

6. Uniform load distribution ensures strong support stability

• Circular streamlined design distributes stress evenly with no stress concentration points.
• Conforms tightly to the surrounding rock surface and securely anchors the rock mass.
• Effectively prevents the expansion of rock mass fractures and rock layer detachment, ensuring durable and stable support.

7. Stable thermal performance; adapts well to various environments

• Heat-resistant, warp-free, and delamination-proof. Resists aging and fading.
• Wide temperature adaptability; maintains stable mechanical performance across diverse environmental conditions.

8. Good electrical performance and sound absorption

• Fiberglass pallets offer excellent electrical insulation and sound-absorbing properties.
• Does not reflect electromagnetic waves; suitable for environments with specific electromagnetic requirements.

Key Features:

• Extremely versatile:Thread parameters perfectly match the fiberglass anchor rod body, ensuring smooth tightening without cross-threading. The plate fits tightly with uniform load distribution, preventing loosening or thread stripping during long-term use.
• Excellent safety performance:Inherits the insulation, anti-static, and spark-free properties of fiberglass materials. Underground operations eliminate the risk of sparks from metal nut collisions, meeting the stringent safety requirements of high-gas mines.
• Outstanding corrosion and weather resistance:Built with a corrosion-resistant resin system to prevent rust and seizing in the damp, corrosive underground environment. Requires no additional maintenance, significantly reducing O&M costs for the support system.
• Easy to install:Can be tightened using standard rock drill rigs without changing special tools. Compatible with existing underground support construction equipment, requiring no additional retrofitting costs.

Selection Principles:

• Strength Matching Principle:Select a tray that matches the anchor rod's load rating to ensure full strength compatibility and prevent failure due to rod perforation.
• Specification Compatibility Requirements:Φ125–Φ140 trays are designed for medium and small diameter bolts in standard support applications; Φ150–Φ170 trays are intended for large diameter, high-load bolts under high-stress and complex conditions. Trays, nuts, and bolts of different specifications must be matched correctly to ensure uniform load distribution and prevent failure due to size mismatch.

Installation and Storage & Shipping Guidelines:

• Trays, nuts, and bolts must be used together as a matched set to ensure the entire system functions cohesively.
• Store the product in a well-ventilated, dry warehouse. Avoid prolonged exposure to direct sunlight to prevent material degradation.
• Avoid impacts from sharp or hard objects during handling to prevent cracking and ensure component integrity prior to installation.

1. Factory-direct supply with quality control and full traceability

The company operates standardized production workshops and fully automated integrated molding lines. From selecting fiberglass raw materials and specialized resins to high-temperature curing, molding, and quality inspection, we maintain full in-house control—no OEM manufacturing or middlemen involved. All FRP round trays are manufactured in strict compliance with mining industry standards. Every batch undergoes rigorous testing for load-bearing capacity, flame retardancy, and anti-static performance. With precise dimensions, stable performance, and certified quality, we ensure zero defective products leave our facility, backed by comprehensive quality assurance. The company is now publicly listed, ensuring standardized governance and transparent operations.

2. Comprehensive specifications, ample stock, and versatile for all construction scenarios

The factory keeps Φ125, Φ140, Φ150, and Φ170 round fiberglass pallets in stock as our four mainstream sizes. We also carry a complete range of fiberglass anchor rods and nuts for all models, enabling one-stop sourcing for full support kits. Whether for temporary or permanent support in standard roadways, deep-well high-stress environments, complex conditions, or slope reinforcement projects, we deliver quickly to avoid construction delays and align perfectly with project schedules. Custom solutions are available to meet unique site requirements or specific anchor dimensions.

3. Product performance upgrade to meet high-standard mining requirements.

Sende New Materials rejects inferior resins and low-grade fiberglass, instead using high-purity fiberglass reinforced with high-strength, corrosion-resistant, and flame-retardant resin. Our products meet strict fiberglass content standards, delivering superior compression strength, resistance to cracking, and minimal deformation. Compared to standard low-cost fiberglass pallets available on the market, Sende offers enhanced flexibility, stable flame-retardant and anti-static performance, and a longer service life against corrosion. Fully compliant with modern mining safety standards, our solutions are engineered for high-risk underground environments. We have successfully secured contracts with major energy companies including Zhongtian Hecreate Energy (Mengkeding Coal Mine), Shendong Coal, Huadian Coal Industry, and Shaanxi Yulin Energy Group for their fiberglass anchor and support material procurement projects. Our product performance and service quality have earned strong recognition from industry-leading clients.
