What is the difference between a web sling and a round sling?

Web slings are flat woven polyester or nylon webbing - the body is a flat strap, and it contacts the load across the full width of that flat face. Round slings have a tubular body with polyester yarn running inside a woven sleeve. That tubular body gives round slings a circular cross-section that contacts the load along a curved profile. For finished or surface-sensitive loads, the flat-face contact of a web sling is typically associated with less surface marking. Configuration options also differ: web slings come in eye-and-eye, twisted-eye, and endless versions, while round slings are endless-loop only.

What materials are available in web slings - polyester or nylon?

Holloway Houston manufactures polyester web slings as the standard catalog offering. Polyester is the more common material for general industrial work and is color-coded by WLL range per WSTDA WS-1 industry convention. Nylon web slings are available for applications where alkaline chemical exposure is a concern - nylon generally performs differently than polyester in alkaline environments. Specific material suitability should be confirmed against manufacturer documentation for the application. Contact our team for nylon web sling stock availability.

What configurations do web slings come in?

Holloway Houston web slings are manufactured in three configurations: eye-and-eye (flat loop at each end, same plane as the body), twisted-eye or turned-eye (eye rotated 90 degrees so it lies flat when hanging vertically from a hook), and endless (a continuous loop with no separate eye, used in basket hitch). Each configuration is suited to different hitch arrangements and load types. The eye-and-eye is the most common starting point for general lifting.

Are web slings manufactured by Holloway Houston or sourced from a third party?

Holloway Houston manufactures web slings at our Houston facility. We produce the slings ourselves - weaving the webbing, assembling the eyes, and tagging the finished product per WSTDA WS-1 industry practice. We are not a pass-through distributor for this product line. Manufactured-in-house means you can trace the sling back to our production facility, confirm specifications directly, and get replacement inventory from the same source without supply chain uncertainty.

What inspection program applies to synthetic web slings?

Synthetic web slings are governed by WSTDA WS-1 (Web Sling & Tiedown Association standard for synthetic web slings). Inspection programs for web slings typically look for cut or abraded webbing, missing or unreadable identification tags, heat or chemical discoloration, eye or stitching damage, and any deformation that affects the sling's ability to carry load. Removal-from-service criteria are product-specific and should follow the manufacturer's documentation. Holloway Houston also offers rigging inspection services for synthetic web slings if you need a formal fleet inspection.

Can web slings be used on finished or coated surfaces?

Web slings are commonly associated with applications involving finished, painted, or coated load surfaces because the flat webbing body distributes contact across a wider surface area than a wire rope, chain, or round sling's tubular profile. That wider flat contact is associated with less localized pressure on the load surface. For specific surface protection requirements — anodized aluminum, polished stainless, glass panels, finished architectural steel - the appropriate sling pad or protective sleeve is typically reviewed alongside the sling selection. Manufacturer documentation and application-specific review govern the actual fit.

Web Sling Types

Web slings are defined by their eye configuration - how the ends are finished determines which hitches the sling accommodates and how it seats against a hook or fixture. Holloway Houston manufactures the three configurations most commonly found in industrial lifting.

Eye-and-Eye Web Slings

Eye-and-eye web slings have a flat loop eye at each end. Both eyes lie in the same plane as the body of the sling. This is the most common web sling configuration and the most flexible: it runs in vertical, choker, or basket hitch without modification. The flat eye seats cleanly on a hook and presents a wide face against the load in basket. Eye-and-eye web slings are the standard starting point for general lifting and rigging work across most industries.

Twisted-Eye (Turned-Eye) Web Slings

Twisted-eye web slings, sometimes called turned-eye web slings, have the eye rotated 90 degrees from the body plane - so the eye lies flat when the sling hangs vertically from a hook. In a straight vertical hitch, the turned eye sits flush against the hook's saddle and keeps the body of the sling from folding or twisting at the attachment point. This configuration is common where riggers are running repeated vertical hitches and want the sling to hang cleanly without manual alignment of the eye each time.

Endless (Grommet) Web Slings

Endless web slings are a continuous loop of flat webbing with no separate eye - the webbing forms a closed ring. Endless web slings are used in basket hitch where the loop runs around the load and both sides share the body of the sling. They distribute load contact over more of the sling length than an eye-and-eye basket, making them a common fit for pipe bundles, structural shapes, and loads where even contact distribution across the contact surface matters.

Endless (Grommet) Web Slings (Type 5)

Endless web slings are a continuous loop of flat webbing with no separate eye - the webbing forms a closed ring. Endless web slings are used in basket hitch where the loop runs around the load and both sides share the body of the sling. Because there are no fixed eyes, the wear points can be rotated around the loop over the life of the sling. They distribute load contact over more of the sling length than an eye-and-eye basket, making them a common fit for pipe bundles, structural shapes, and loads where even contact distribution across the contact surface matters. See the full Web Slings catalog for all three configurations in stock.

Web Sling Materials

The webbing material determines how the sling behaves in the presence of chemicals, moisture, heat, and UV exposure. Two materials cover the majority of industrial web sling applications.

Polyester Web Slings

Polyester is the standard material for web slings across most industrial applications. Polyester webbing is color-coded by WLL range per WSTDA WS-1 industry convention - the color on the sling tag and body corresponds to its assigned working load limit range, not to a specific single capacity. Polyester web slings are generally associated with better performance in acidic environments compared to nylon, and they show lower elongation at working load than nylon webbing. The majority of web slings in the Holloway Houston catalog are polyester.

Nylon Web Slings

Nylon webbing is typically associated with applications where alkaline exposure is a concern - nylon generally performs better in alkaline chemical environments where polyester may be less suited. Nylon web slings elongate more at working load than polyester, which can be a consideration where load movement during the lift is a factor. Specific chemical and environmental suitability for either material should be confirmed against manufacturer documentation and WSTDA WS-1 guidance for the application at hand.

Where Web Slings Are Used

The flat body of a web sling is what sets it apart in the field. A round sling's tubular core contacts the load along a curved line of circumference. A web sling's flat face contacts the load across the full width of the webbing - and that wider footprint changes the pressure distribution on the load surface. This is why web slings are a common first choice for glass panels, finished steel, painted surfaces, and automotive body components, where the sling's contact mark matters. Industries where web slings are routinely specified include steel service centers, construction and precast handling, glass and panel fabrication, manufacturing assembly lines, and automotive and transportation equipment manufacturing. Web slings also see regular use in marine and offshore work for cargo handling where the load's finish or structural profile needs a non-marring, wide-contact synthetic option.

Web Slings vs. Round Slings

Web slings and round slings are both flat-color, synthetic, polyester slings - but the similarity stops at the material. The body design is different, and those differences show up at the point of contact with the load.

	Web Slings	Round Slings
Body design	Flat woven webbing	Tubular endless core, polyester yarn inside a sleeve
Load contact surface	Wide flat face contacts the load	Circular cross-section; load contact is along the curve of the tube
Eye configurations	Eye-and-eye, twisted eye, endless	Endless loop only
Common hitch types	Vertical, choker, basket	Basket most common; vertical and choker possible
Typical cost position	Generally lower	Varies; often higher for equivalent capacity

The choice between web slings and round slings typically comes down to the load surface, the hitch configuration, and what the application calls for. Round slings wrap around a load and cradle it with the tubular body - the round profile can seat into grooves and flanges on certain load shapes. Web slings lay flat against the load face and hold that contact across the webbing width. That flat-to-flat contact is the reason web slings are common on finished or fragile surfaces where the contact pattern of a tubular sling would concentrate pressure along the tube's curved contact line.

Ratings and examples here are for safety awareness. Sling selection should follow manufacturer documentation, applicable WSTDA guidance, and qualified review for the specific application.

Web Sling Inspection and Service Life

Synthetic web slings are inspected per WSTDA WS-1 industry guidance, which addresses inspection frequency, in-service inspection, and removal-from-service indicators. Inspection programs for web slings typically look for deformation, cut or abraded webbing, discoloration or heat damage, chemical attack, missing or unreadable identification tags, and damage to the eye area or stitching. Product-specific removal criteria follow the applicable manufacturer documentation and WSTDA WS-1 guidance - no numeric wear thresholds appear here because those criteria are product-specific and must come from the manufacturer.
