Introducing the high-quality Utility Pole Alley Arm Brace from Jinmai Powerline, a leading manufacturer in pole line hardware. Our Alley Arm is meticulously designed and manufactured to ensure optimal support and alignment for power distribution and transmission lines. With a commitment to excellence, we adhere to rigorous standards such as ASTM A123 and ASTM153 for hot dip galvanizing, resulting in a smooth, rust-free surface that guarantees durability and longevity.
Material: Constructed from premium angle steel, our alley arms are chosen based on the BS4360 standard, ensuring straightness and freedom from defects such as scale or blisters. While steel is the primary material, options for aluminum or wooden alley arms are available depending on specific applications.
Design: The alley arm features a unique design with one straight edge and the other slightly bent, providing a robust support structure. It is commonly mounted at a 45-degree angle to the pole, facilitating proper alignment and stability for overhead lines and hardware.
Technical Specifications: Available in various lengths (60", 84", and 120"), the width and thickness of our alley arms are customizable to suit different applications. The hot-dip galvanized finish not only offers a smooth, bright appearance but also conforms to the ASTM123-78 standard, ensuring corrosion resistance and protection against environmental factors.
Installation: Our alley arms are designed for straightforward installation. With the necessary tools and equipment, positioning and securing the alley arm to the pole is a simple process. The use of lag screws and machine bolts ensures a tight and stable fit, providing the necessary rigid bracing for power lines and distribution hardware.
Applications: The versatility of our alley arms makes them suitable for a wide range of uses, including overhead lines, power poles, utility poles, and lighting poles. They play a crucial role in maintaining the stability of power transmission and distribution systems.
Material Selection and Procurement: The first step in our manufacturing process is the selection of high-quality angle steel that meets the stringent BS4360 standard. This material is chosen for its structural integrity and resistance to environmental factors, ensuring the final product's longevity.
Design and Engineering: Our engineering team utilizes advanced CAD software to design the alley arms according to customer specifications and industry standards. This step ensures precision in dimensions, weight, and structural design to meet the diverse needs of our clients.
Cutting and Shaping: Once the design is finalized, the raw angle steel is cut to the required lengths using state-of-the-art cutting machines. The cutting process ensures accuracy and minimizes material waste. The cut pieces are then shaped into the desired form, including the creation of the slightly bent edge, using bending machinery.
Drilling and Tapping: Holes for lag screws and machine bolts are precisely drilled into the alley arms. These holes are critical for the installation and secure fastening of the product. Tapping is performed to create internal threads that will accommodate the bolts, ensuring a secure fit when installed.
Galvanization: To protect the alley arms from corrosion and ensure a long service life, they undergo a hot-dip galvanization process. This involves coating the steel with a layer of zinc by submerging it in molten zinc at high temperatures. This process conforms to the ASTM123-78 standard, resulting in a smooth, rust-free, and aesthetically pleasing finish.
Quality Control and Inspection: Each alley arm undergoes a thorough quality control check. This includes visual inspections, dimensional checks, and strength testing to ensure that each piece meets our high-quality standards and the specifications provided by the client.
Packaging and Shipping: Finally, the finished alley arms are carefully packaged to protect them from damage during transit. They are then shipped to our clients or stored in our facility until required.
Material: The primary material used, conforming to the BS4360 standard for structural quality and durability.Aluminum or wood may be used for specific applications or customer preferences.
