Heavy-Duty Polyurethane Coil Storage Pads & Saddles

Steel coils may remain stationary under high contact loads for extended periods. Storage-pad selection should address compression, coil stability, surface marking, rack geometry, contaminants, environment, and inspection requirements before a support system is approved.

当社は製造しています 鋳造ポリウレタン coil storage pads for steel handling applications. Hardness is only one design input; compression set, contact area, coil diameter, support geometry, temperature, fluids, surface finish, and allowable deformation should be reviewed together.

Hardness, core substrate, geometry, dimensions, color, and surface can be reviewed for hot- or cold-rolled coil racks. Tooling, sample timing, and production schedule are quoted from the drawing, quantity, material, and inspection requirements.

高耐久性ポリウレタン製コイル用支持パッドおよびサドルの産業用途

Molded PU coil supports can be considered for static rack systems in steel production, metal distribution, and aluminum processing after indoor or outdoor service conditions are defined.

Technical Selection Factors for Polyurethane, Rubber, and Other Coil Supports

Compare candidate support materials with the same test methods and acceptance criteria. Relevant checks may include abrasion, tear behavior, compression set, UV exposure, chemical compatibility, marking, and retained geometry.

– Compare abrasion data for the selected polyurethane and alternative materials under the same method, load, wheel, and endpoint.

– For outdoor storage, specify UV and weathering acceptance criteria for color, cracking, hardness, and surface condition.

– Review tear behavior and edge geometry using data from the selected grades and representative contact conditions.

– Test non-marking and indentation risk on the actual polished, painted, galvanized, or stainless surface.

– Calculate load distribution through the pad and rack structure with the responsible rack or structural engineer.

– Evaluate one-piece or modular construction for retention, installation, replacement, and movement during handling.

Procurement and Quality Questions for Custom Polyurethane Coil Pads

Procurement should compare supplier capability, material records, tooling, sample approval, inspection, packing, delivery, and support against the project requirements.

– Request the specific management-system certificates, material records, and test reports required for the order.

– Confirm tooling ownership, drawing control, sample timing, and production lead time in the quotation.

– Confirm sample and production quantities from part size, tooling, material, and order requirements.

– Compare total landed cost, inspection, installation, service evidence, and replacement risk.

– Provide coil, rack, load, environment, and drawing data for design-for-manufacture review.

– Record warranty scope, exclusions, acceptance criteria, and claim process in the order.

– Agree the batch inspection and test report requirements before production.

Coil Storage Pad Application Examples and Validation Plans

The following application examples show what to document when existing coil supports crack, deform, move, or mark stored material. They are validation templates, not verified customer performance claims.

Application Example 1: Cold-Rolled Stainless Coil Storage

– Observed condition: Existing saddles show wear, movement, or marking on surface-critical coils.

– Engineering review: Record coil mass and diameter, contact area, rack geometry, saddle fit, surface finish, hardness, and material compatibility.

– Validation plan: Inspect coil surfaces, pad wear, deformation, movement, rack contact, and replacement triggers during a representative storage trial.

Application Example 2: Outdoor Hot-Rolled Coil Yard

– Validation plan: Define outdoor exposure, inspect color and cracking, measure pad deformation, and keep rack inspection intervals under the site engineering plan.

– Observed condition: Existing pads show weathering, cracking, movement, or loss of support geometry outdoors.

– Engineering review: Compare UV-stabilized formulations, support geometry, reinforcement, drainage, retention, and rack compatibility.

Polyurethane Coil Pad and Saddle Selection Guide for Steel Rack Engineers and Buyers

Use the following workflow to define a coil support for the actual load, rack, coil surface, environment, and validation requirements.

手順 1：サドル接触面積あたりのコイルの最大静荷重を確認する

Calculate coil load per support, contact area, pressure distribution, dynamic handling factors, rack reactions, and allowable pad deformation.

ステップ 2：保管環境における紫外線照射レベルを定義する

– Indoor covered yards: compare candidate formulations for load, compression, fluids, temperature, and marking.

– Open-air yards: define UV and weathering acceptance criteria for water, drainage, temperature, color, cracking, and retained support geometry.

ステップ3：化学物質への曝露および残留腐食防止潤滑剤の分析

Identify anti-rust coatings, slitting oils, cleaners, water, and other chemicals. Compare candidate ポリエステル系ポリウレタン および ポリエーテル系ポリウレタン grades using compatibility data and representative immersion or contact tests.

ステップ4：コイルの表面仕上げ要件に合わせてショア硬度を調整する

– Surface-critical coils: prioritize contact-area design, cushioning, clean formulation, and marking tests.

– Rough hot-rolled coils: evaluate load, indentation, abrasion, impact, support, and allowable deflection.
