As a trusted manufacturer since 1998, Anping County Boli Hardware Wiremesh Products Factory specializes in producing high-quality flat endless slings for demanding construction site lifting. Our 5:1 Safety Factor flat endless sling, designed in a 20 ft (6.1 m) length, is engineered specifically for lifting heavy steel beams with maximum reliability. With annual export value exceeding US$5 Million and a global customer base across North America, Europe, Southeast Asia, and beyond, we bring decades of industrial rigging expertise to every product. This sling combines robust polyester construction with a seamless endless design, offering superior load distribution and abrasion resistance for the toughest jobs.

Key Features & Technical Specifications

5:1 Safety Factor – Built with a high safety margin to ensure reliable lifting under heavy loads, exceeding standard industry requirements.
Endless Flat Loop Design – No stitching or sewn joints, reducing weak points and extending service life. The seamless loop provides even load distribution and eliminates sharp edges that could damage the load.
High-Strength Polyester (PES) Webbing – Resistant to UV degradation, moisture, and most chemicals, making it ideal for outdoor construction environments.
20 ft Length (6.1 m) – Versatile length for wrapping around large steel beams, columns, or structural elements. Easily adjust choking angles for optimal grip.
Wide Load Capacity Range – Available in multiple widths (1", 2", 3") to suit different beam sizes and weight requirements. Custom capacities available upon request.
Abrasion-Resistant Edge Protection – Reinforced edges with protective sleeves minimize wear when dragging over concrete or rough steel surfaces.
Color-Coded Identification – Standard orange or yellow for high visibility, with optional color-coding for load capacity tagging.

Easy Handling & Setup – Lightweight and flexible, the endless loop can be quickly choked or basket-hitched around steel beams without complex rigging.
Protects Load Surface – The soft polyester webbing does not scratch or mar painted steel surfaces, preserving beam integrity.
Cost-Effective – Long service life reduces replacement frequency, and the seamless design minimizes maintenance downtime.

Frequently Asked Questions (FAQ)

What is the maximum load capacity of this 20 ft flat endless sling?
Load capacity depends on the width and configuration. For example, a 2-inch wide sling in a choked hitch can typically support several tons. Contact us with your specific load requirements for exact capacity data.
Can I get a different length or width?
Yes, we offer custom lengths and widths. Minimum order quantities may apply. Please provide your preferred dimensions for a tailored solution.
Is this sling suitable for outdoor use in rainy or humid environments?
Absolutely. Polyester webbing is inherently resistant to moisture, mildew, and UV radiation, making it ideal for outdoor construction sites.
How do I inspect the sling for wear and tear?
Regularly check for cuts, abrasion, broken fibers, or heat damage. The seamless design reduces hidden defects, but visual inspection before each use is recommended.
Does this sling come with a certificate of compliance?
Yes, we can provide a certificate of conformance upon request. Third-party load testing reports are also available.
Can I use this sling for lifting concrete beams or pipes?
Yes, it is suitable for any cylindrical or rectangular load where a flat loop can be choked or basket-hitched. For sharp edges, use edge protectors to prevent cutting.
What is the minimum bending radius for this sling?
The sling should not be bent sharply around corners with a radius less than the sling width. Always use corner protectors on sharp edges to maintain the 5:1 safety factor.
Do you offer different colors for load rating identification?
Yes, we can produce slings in standard colors (orange, yellow, green, etc.) to match your internal load rating system. Please specify your color-coding requirements.
