Each inside diameter is paired with a maximum book-block thickness. Purchasing teams can therefore place thin and thick binding jobs under one YPS steel coil supply program without applying the same diameter to every SKU.
YPS Steel Single Spiral Coil for Bookbinding
Order a custom metal spiral binding coil around the book you actually produce. YPS supplies 16 published inside diameters, paired wire sizes, 6 or 8 mm pitch options and Pantone-matched coatings for printers, notebook manufacturers and binding-supply distributors.
Description
Compare YPS Steel Single Spiral Coil Specifications
Start with the finished book-block thickness, choose the matching inside diameter, and then verify the paired wire diameter and pitch. These published limits let buyers compare every YPS steel spiral binding coil size without guessing from page count alone.

Not sure which steel bookbinding coil fits your punch? Send the finished book thickness and a clear photo or sample of the punched edge. The YPS metal spiral coil team can use those details to narrow the quotation to the compatible published size and pitch.
Choose a Single Spiral Coil That Fits Your Book Block
A reliable coil specification comes from three things the buyer can verify: finished binding thickness, punch pattern and required appearance. A generic book size is not enough.
Book thickness
Choose among 16 published sizes covering maximum binding thicknesses from 3.4 to 42.8 mm. This keeps the coil proportionate to the book block instead of forcing one diameter across unlike jobs.
Punch pattern
Use 6 mm pitch for the smaller 6.4–12.7 mm inside diameters. From 14.3 to 50.8 mm, the published range allows 6 or 8 mm pitch, subject to the punched document and production equipment.
Visual match
Specify a Pantone color reference for a custom steel single spiral coil that supports cover artwork, stationery collections or a defined house palette.
Wholesale Steel Single Spiral Coil Advantages for Print Buyers
Diameter follows the finished binding thickness
6 or 8 mm options match different punched patterns
Pitch is checked against the document instead of assumed from the coil appearance. This is the first compatibility question a wholesale steel spiral coil buyer should settle because the wrong pitch will not feed correctly through the punched edge.
Pantone references connect the coil to the cover
A Pantone reference gives YPS a defined coating target. Buyers can approve the physical coil against the cover rather than accept a generic color name that may shift between orders.
Nylon Coated Steel Spiral Binding Coil with a Smooth Finish
The steel wire is covered with a smooth nylon coating described as strongly bonded and resistant to peeling or breaking. For a printer or notebook producer, the value is a cleaner visible spine and a surface designed for repeated handling.
What to inspect before releasing a bulk order
The product record describes an innocuous material, an environmentally protective coating, wear resistance, heat resistance and aging resistance. Ask YPS to align the production order with the approved sample for coating continuity, smooth feeding and color consistency. If your market requires a named certificate or test report, put the exact document requirement in the RFQ for confirmation.
YPS Steel Spiral Binding Coil for Notebook and Print Projects
This metal bookbinding coil is intended for projects where the spine must fit both the punched paper block and the cover design. YPS can quote it by size, pitch, loop count and Pantone reference instead of treating every print run as the same product.
Custom notebooks and journals
Match the steel binding coil to a cover color, then choose the inside diameter from the finished paper-block thickness. Include the exact loop count in the quotation.
Manuals and working documents
Use the specification table to separate thinner and thicker document runs. Confirm 6 or 8 mm pitch against the punch before ordering the single spiral coil.
Stationery and print programs
Pantone color selection supports collections that need a repeated visual standard. Approve the actual coated sample rather than relying only on an on-screen color.
This product is a strong fit for print shops, notebook manufacturers, stationery brands and binding-supply distributors that can provide a defined specification and order quantity. If you only know the page count, send the paper stock and finished book thickness as well so YPS can quote from measurable requirements.
Custom Steel Single Spiral Coil Manufacturing for Project Buyers
Give YPS four production inputs: pitch, size, loop count and color. That turns a general inquiry into a custom metal spiral coil quotation your sourcing and production teams can actually evaluate.
State 6 or 8 mm and identify the punched pattern or equipment requirement.
01
Use the maximum binding thickness to select the inside and paired wire diameter.
02
Provide the loop quantity per coil and the required Pantone color reference.
03
YPS steel spiral coil samples are available. The published preparation time is 1–2 days after payment and confirmed documents, with courier cost paid by the buyer.

How YPS Verifies a Steel Single Spiral Coil Order
Put diameter, wire size, pitch, coating condition and approved color into the purchase specification so both sides inspect the same points. If your customer requires a named certificate, test method or report, add it to the RFQ and ask YPS to confirm the current order-specific document.
Bulk Steel Spiral Binding Coil Packaging and Shipping Requirements
Include the required packing unit, carton label, order quantity and destination in the RFQ. YPS can then confirm the packaging and shipping terms for the wholesale steel binding coil order before you release the purchase order.
MOQ and Lead Time for YPS Steel Single Spiral Coil Orders
MOQ
MOQ is confirmed against one defined diameter, pitch, loop count and color combination. Put every variation and its quantity on the RFQ so the final minimum is clear before sampling.
Sample timing
The YPS product page states a sample preparation time of 1–2 days after sample payment and confirmed documents. Samples ship by courier, with shipping cost assigned to the buyer.
Payment terms
The source page lists 30% deposit with 70% balance before delivery, deposit plus balance by letter of credit, 100% advance payment, Western Union and PayPal. Confirm the applicable option on the quotation.

Why Buyers Choose YPS as Their Steel Spiral Coil Manufacturer and Supplier
YPS identifies itself as a factory rather than a trading company and supplies the metal spiral binding coil to a buyer-defined specification. You can place the inside diameter, wire diameter, pitch, loop count and Pantone color on one RFQ, then request a physical sample before the main order. This gives sourcing teams a practical way to evaluate YPS as a custom steel coil supplier. Buyers planning a wider product range can also review the YPS metal spiral coil binding range and custom coil binding service.

Steel Single Spiral Coil Procurement Questions Answered
What does a steel spiral coil supplier need for a custom quotation?
Provide the required pitch, inside diameter or book-block thickness, loop count, color reference and order quantity. YPS can then review the requested combination against the published size range instead of returning a generic price.
Which inside diameter should I choose for my book thickness?
Match the measured finished book block to the "Maximum Thickness" column and select the corresponding inside diameter. The published range covers 3.4–42.8 mm maximum thickness with inside diameters from 6.4 to 50.8 mm.
Is the custom single spiral coil available in 6 mm and 8 mm pitch?
Yes, but availability depends on coil size. The 6.4–12.7 mm inside diameters are listed in 6 mm pitch; the 14.3–50.8 mm sizes are listed with 6 or 8 mm pitch. The selected pitch must match the punched document.
Can the coated steel binding coil match a brand color?
Yes. YPS accepts Pantone references for custom colors. Send the code with the RFQ and approve the coating on a physical sample before bulk production.
How quickly can I receive a steel spiral coil sample?
YPS states that samples are ready for delivery within 1–2 days after sample payment and confirmed documents. They are sent by courier, and the buyer pays the shipping cost.
What payment methods are published for this product?
The listed choices include 30% deposit and 70% balance before delivery, a deposit with balance by letter of credit, 100% in advance, Western Union and PayPal. YPS will need to confirm which term applies to your steel single spiral coil order.
