What is the difference between a coil pad and a coil cradle?

A coil pad generally describes the contact component beneath a coil. A cradle usually describes a shaped support or support assembly. Because names vary, specify the geometry, mounting arrangement and intended function rather than relying on the product name alone.

How much weight can a polyurethane coil saddle support?

There is no single capacity that applies to all polyurethane coil saddles. A rating depends on the formulation, geometry, contact conditions, loading duration and supporting assembly. Provide the complete application details for review; hardness alone is not a load rating.

Can a replacement part be developed from an existing sample?

Willsup works from drawings and samples for custom polyurethane projects. For a coil support application, include the installed dimensions and operating conditions. The sample provides a starting point for evaluation rather than evidence of the original load rating.

Are polyurethane coil pads suitable for polished or coated metal?

Suitability depends on the formulation and the actual contact conditions. Identify the surface finish, cleaning requirements and acceptable marking limits, then confirm performance with appropriate testing before specifying the component.

What affects price and lead time?

Part size, geometry, formulation, tooling, quantity and validation requirements affect a custom project’s cost and schedule. Provide drawings and order quantities so the quotation can address your actual requirements.

Polyurethane Coil Storage Pads, Saddles & Cradles

Custom polyurethane components for metal coil storage applications

Protecting a finished coil starts with the surface it rests on. The support profile, contact area and material all matter when specifying coil storage pads for steel, aluminum or other surface-sensitive metals.

Three blue polyurethane coil storage components: a flat pad, a shaped saddle and a small cradle insert — Flat pad, shaped saddle and cradle insert — cast in polyurethane to the profile of the coil they support.

Bring Willsup your drawing, existing component or application requirements to discuss a custom polyurethane solution. Our Canadian manufacturing capabilities include mold design, polyurethane molding and precision finishing for demanding industrial applications.

Find the right component for your coil storage system

Polyurethane coil storage pads sit between a metal coil and its supporting surface. Saddles and cradles use shaped contact surfaces to accommodate the coil profile. The right configuration depends on the coil dimensions, loading conditions and supporting structure.

Use the comparison below to define your requirement before requesting a quote. Product terminology varies between suppliers; a drawing is the clearest way to specify the component you need.

Component	Purpose	Information to provide
Coil storage pads	Provide a contact layer between the coil and a supporting surface	Pad footprint, thickness, contact location and attachment requirements
Coil saddles	Provide shaped contact surfaces suited to a defined coil geometry	Coil diameter range, saddle profile, support spacing and mounting details
Coil cradles	Form part of an arrangement that supports and locates a coil	Assembly drawing, coil orientation, base structure and restraint requirements
Replacement polyurethane inserts	Renew the contact component within an existing assembly	Original drawing or sample, interface dimensions and observed wear

A polyurethane component is one part of the storage arrangement. The complete assembly — including its base, anchors, restraints and any stacking configuration — needs a defined design and load rating.

Specify around your coil, your surface and your workflow

For steel coil storage solutions, total coil weight is only the starting point. Two coils with the same weight can impose different demands on their supports because of their diameter, width, contact geometry and loading method.

Describe how your coils arrive, where they rest and how they are removed. Include any damage or wear you are trying to address: surface marks, permanent deformation of the existing pad, cracking, loose inserts or difficulty matching replacement parts.

For coated or polished material, identify the finish and its acceptance criteria. Surface protection depends on the selected formulation, contact pressure, cleanliness and operating conditions. Where marking is critical, include a representative contact test in the approval process.

New storage arrangements

Share the proposed layout and component drawings. Identify the coil size range and how the supports connect to the floor, rack or frame. This gives the project team a basis for reviewing the polyurethane component within the wider assembly.

Replacement coil pads and inserts

An existing part can help define fit, but wear may have changed its original dimensions. Supply the assembly drawing if available, photographs of the installed component and a description of the failure. Willsup’s custom manufacturing process can start from drawings or samples, with feasibility confirmed for the application.

Changing coil sizes or operating conditions

A change in coil weight, diameter, temperature or storage duration calls for a review of the support specification. Provide both the current conditions and the proposed range so the component is evaluated for its intended service.

What determines the polyurethane specification?

Shore hardness is one selection factor. It does not establish the allowable load of a coil saddle or prove that a storage assembly is suitable for stacking.

Design input	Why it matters
Maximum coil weight and load cases	Defines the loading the component and assembly must accommodate
Coil diameter, width and orientation	Establishes the contact geometry and fit
Support layout and contact area	Helps the designer assess load distribution
Time under load	Establishes the sustained-loading conditions to evaluate
Temperature and chemical exposure	Informs formulation selection and compatibility review
Coil finish	Defines surface-contact and marking requirements
Mounting and surrounding structure	Establishes interfaces, retention and installation constraints

For background on material selection, read our polyurethane Shore hardness guide. Final material and component specifications should be confirmed against the application requirements.
