What standard governs the color coding of flat webbing slings?

The international standard EN 1492-1 (European Standard) and ISO 4878 define the color coding system for synthetic flat webbing slings. Each color corresponds to a specific Working Load Limit (e.g., Violet = 1T, Green = 2T, Yellow = 3T, Red = 5T).

What do the black capacity lines on a colored webbing sling mean?

Each woven black stripe line represents 1 Ton of Working Load Limit (WLL). For example, a yellow sling with 3 black lines indicates a 3-Ton rating, providing a secondary visual check alongside color identification.

Color-Coded Flat Webbing Slings (EN 1492-1 1T-12T)

Tie Shou color-coded flat webbing slings are premium industrial synthetic lifting belts manufactured in strict compliance with EN 1492-1 and ISO 4878 international standards. Woven from 100% high-tenacity polyester (PES) yarn, these color-coded slings allow immediate, error-free Working Load Limit (WLL) identification on jobsites, supporting rated capacities from 1 Ton (Violet) up to 12 Tons+ (Orange) with safety design factors of 5:1, 6:1, and 7:1.

Key Safety Features & Quality Standards:

Standardized Color Identification: International color coding prevents accidental overload and simplifies visual safety checks during complex rigging operations.
Black Capacity Stripe Lines: Woven black stripe indicators (1 stripe = 1 Ton WLL) provide secondary tonnage verification even in harsh environments.
Reinforced Lifting Eyes: Double-ply stitched loop eyes coated with protective polyester sleeves reduce wear at crane hook contact points.
Low Elongation & Weather Resistance: Highly resistant to UV radiation, moisture, and mild acids, with working elongation under 3% at rated capacity.
