Siamnet Industry Co., Ltd.

A “knitting net”, sometimes known as a “raschel net,” “knitted shade net,” or “sunshade net knitting,” is made from high-density polyethylene (HDPE) yarns that are interlaced using a knitting process — similar to how yarn is woven in textiles — rather than the conventional weaving or extrusion method. This knitting technique gives the net superior strength, flexibility, and multidirectional tension resistance, making it ideal for demanding industrial and agricultural applications.

At Siamnet Industries Co., Ltd., a trusted knitting net manufacturer in Thailand, knitting net that produce from our factory can be customized in order to match with various functional needs. These include safety nets for construction, cargo cover nets, and aquaculture nets — all engineered for safety, elasticity, and long-term durability far beyond typical woven mesh products available in the market.

High-Performance Fibers and Quality Control

Our knitting net in Thailand is crafted using high-grade HDPE yarns that undergo rigorous selection and quality testing, particularly focused on tensile strength — a crucial indicator of fiber performance.

Throughout the production process, we implement a systematic quality control protocol. Samples are tested according to ASTM D5034 standards, measuring tensile force while also examining the knit pattern and fabric density to ensure uniformity and reliability across every roll delivered to our clients.

To further enhance long-term durability, each knitted shade net is produced using HDPE yarns that include specialized stabilizers and additives:

• UV Stabilizer – protects against ultraviolet degradation during prolonged outdoor use.

• Antioxidants – slow down polymer deterioration caused by heat and oxygen exposure.

• Antistatic Agents – prevent dust adhesion, making the net cleaner and easier to maintain.

Adaptability to Harsh Environments

The HDPE knitted net is exceptionally suited for high-humidity or underwater environments, such as fish cages, pond enclosures, or marine farming, due to the following characteristics:

• Non-absorbent – prevents swelling or deformation when exposed to water.

• Rot-resistant – maintains strength and texture even after prolonged submersion.

• Shape-retentive – does not stretch or sag under moisture, ensuring dimensional stability.

• Non-rebound property – absorbs impact without recoiling, minimizing risks of damage or injury.

These properties enable the net to maintain its structure and functionality over time, even under challenging conditions. Moreover, it offers better resistance to saltwater corrosion and chemical degradation compared to conventional fibers such as nylon or polyester, which often soften or lose integrity in damp or submerged environments.

Additionally, underwater installations are not exposed to direct sunlight, reducing UV deterioration and thus extending the product’s service life even further.

Quality Inspection Before Delivery

As a trusted knitting net supplier, we perform thorough inspections to ensure every product meets international standards before shipment. The quality checks cover:

• Structural and Pattern Inspection – every roll is rechecked post-production for defects or inconsistencies before careful packing and dispatch.

• Tensile Strength Testing – performed using ASTM D5034-certified machines to verify that the net can endure operational tension effectively.

• Color and Fabric Uniformity Check – ensuring consistent hue and texture across the entire raschel net.

With years of expertise as a knitting net factory in Thailand, we continuously strive to deliver high-performance knitted nets designed for durability, versatility, and value — the perfect balance between engineering precision and craftsmanship. Whether you need sunshade net knitting for agriculture or heavy-duty knitted shade net for construction, our products embody reliability woven into every thread.

In agriculture, industry, and even household usage, shading nets are far more than just materials for sun protection or light filtering. A high-quality shading net helps reduce heat inside greenhouses, protect crops from excessive sunlight, and control temperature in industrial yards. That’s why a shading net plays an essential role in creating a comfortable and efficient environment for every application.

Unlike conventional materials, shading nets are engineered to balance not just the amount of light but also the quality and direction of light — factors that directly affect plant growth, visibility, and shading efficiency in different settings.

At Siamnet Industry, we manufacture our products using 100% High-Density Polyethylene (HDPE) yarn, ensuring long-lasting strength, flexibility, and resistance to UV rays and harsh weather. As a trusted shading net factory in Thailand, our products are widely recognized for their superior performance and durability.

Key advantages include:

• Excellent UV resistance without becoming brittle or fragile

• Stable and smooth tension when installed

• Easy to fold, roll, or shape without deformation

Two Main Types of Shading Net Structures

1. Woven Structure

Produced using the same technique as textile weaving, this type consists of two main components:

• Warp yarns: round HDPE monofilaments providing structure and tension

• Weft yarns: flat HDPE yarns allowing flexibility and an even surface

This design ensures consistent shading density and prevents fiber loosening over time. It is widely used as a black shading net or shading net for greenhouse applications requiring clean appearance and even light distribution.

2. Knitted Structure

These feature intricate weave patterns that enhance both strength and flexibility. They are ideal for areas requiring broad coverage without rigid frameworks—such as greenhouses, windy environments, or design projects that demand unique shapes.

The knitted structure can also be customized with specific patterns, such as diagonal weaves, grid designs, or semi–double-layer shades, to achieve targeted light filtration and aesthetic effects. Patterns like diagonal, grid, or double-layer knitting can be customized, making it a popular choice for both construction net and shading net for plants.

Quality Control and Testing

As a shading net manufacturer and shading net supplier, we maintain rigorous quality standards:

• Tensile strength testing under ASTM D2256 to ensure durability under real-world conditions

• Field testing under sunlight, strong winds, humidity, and open-air exposure to analyze fiber performance

• Continuous product development based on customer feedback and in-house trials
