The Control of Steel With the Benefits of Graphite

SteelFiber technology is designed for golfers who want stability, consistency and responsive feedback without the weight and vibration commonly associated with traditional steel shafts.

01

Graphite Composite Core

The graphite core helps reduce unwanted vibration while supporting a smoother feel, improved comfort and a lighter overall shaft design.

02

SteelFiber Outer Mesh

An ultra-fine steel-fiber layer surrounds the graphite core to improve stability and resist unwanted twisting during the swing and through impact.

03

Constant Weight Construction

Every shaft within a selected model and flex maintains the same weight, regardless of its raw length, helping create consistent feel throughout the iron set.

SteelFiber Construction

Thousands of Steel Fibers Over a Graphite Core

More than 59 miles of extremely fine steel fiber are used in the outer mesh of a SteelFiber shaft. This structure is engineered to combine graphite’s vibration-dampening properties with the stability and control golfers expect from steel.

Important: SteelFiber CW shafts are .355-inch taper-tip, length-specific shafts. They do not require tip trimming. Select the appropriate raw shaft length for each iron and perform final playing-length adjustments from the butt end in accordance with the manufacturer’s installation instructions.

Choosing a SteelFiber Weight

Shaft weight affects timing, speed, balance and feel. The proper choice depends on your current shaft, transition, desired club weight and preferred impact sensation.

i70 and i80 CW

Lighter options for golfers seeking easier clubhead speed, less fatigue and reduced overall club weight while maintaining more stability than many conventional lightweight graphite designs.

i95 CW

A versatile middle-weight option that balances speed, stability and feel. It can suit golfers moving from steel into graphite without making an extreme reduction in shaft weight.

i110 and i125 CW

Heavier profiles for golfers who prefer substantial shaft weight, stronger feedback and enhanced control while still benefiting from SteelFiber’s vibration-dampening graphite core.

These fitting descriptions are general guidance and do not replace a professional fitting. Flex should be selected based on the golfer’s complete delivery and feel preference—not swing speed alone.
Component and Custom-Build Options

Build SteelFiber Into Your Iron Set

SteelFiber CW can be selected as a replacement component or incorporated into a compatible custom iron build. Confirm the clubhead’s hosel diameter and the correct length-specific shaft before installation.

  • Select the appropriate weight and flex
  • Confirm .355-inch taper-tip head compatibility
  • Match each shaft length to its intended iron
  • Select the desired grip and grip size
  • Choose component-only or available assembly options

Frequently Asked Questions

What does CW mean?
CW means constant weight. Every shaft within a selected SteelFiber CW model and flex has the same nominal weight, even though the raw shaft lengths differ throughout the set. This creates more consistent shaft weight from the long irons through the short irons.
What is SteelFiber technology?
SteelFiber construction combines a graphite composite core with thousands of extremely fine steel fibers wrapped around the shaft. The graphite core helps dampen vibration, while the steel-fiber surface layer adds stability and resistance to twisting.
Do SteelFiber CW shafts require tip trimming?
No. SteelFiber CW shafts are length-specific taper-tip shafts and do not require tip trimming. Final playing-length adjustments are made from the butt end after the correct raw shaft has been matched to its intended iron.
Will these shafts fit every iron head?
No. SteelFiber CW shafts have a .355-inch taper tip and are intended for compatible .355 taper-tip iron heads. A .370-inch parallel hosel requires a different shaft configuration or appropriate professional installation work. Always verify compatibility before ordering.
How does SteelFiber compare with a traditional steel shaft?
SteelFiber is designed to provide steel-like stability and control while reducing vibration through its graphite core. Depending on the selected model, it can also reduce overall shaft and club weight compared with many traditional steel options.
Are these shafts sold individually or as a complete set?
Ordering options depend on the selections offered on this product page. Because SteelFiber CW shafts are length-specific, verify the selected raw length and intended iron for every individual shaft or set before completing your order.

Product-specific terms control. A product page, written quote, order confirmation, or manufacturer policy may list a different lead time, return window, cancellation charge, restocking fee, or final-sale condition. When it does, those product-specific terms apply to that item.

Shipping and fulfillment

Where we ship

Our standard online shipping options apply to eligible addresses within the contiguous United States. Shipping to Alaska, Hawaii, U.S. territories, or international destinations may require a separate quote and may not be available for every product.

We may be unable to ship certain products to P.O. boxes, APO/FPO addresses, or locations that cannot accept freight delivery. Please contact us before ordering if your address has special delivery restrictions.

Shipping charges

Products marked as eligible for free shipping will ship free by the standard method stated on the product page or at checkout. Oversized, heavy, freight, expedited, remote-area, installation-related, or special-handling charges may apply. Any available shipping charge will be displayed at checkout or included in a written quote.

Inventory and manufacturer-direct shipping

Grater Golf holds inventory for some products. Other products—including many launch monitors, projectors, simulator enclosures, impact screens, mats, components, and accessories—may ship directly from the manufacturer or distributor. This helps reduce handling time but may result in separate packages, different carriers, and more than one tracking number.

An “in stock” indication may reflect inventory held by Grater Golf, a manufacturer, or a distribution partner. Availability is subject to final confirmation. If an item is unavailable, delayed, or backordered after an order is placed, we will contact you with available options.

Processing and lead times

Estimated processing or lead times shown on product pages are business-day estimates, not guaranteed delivery dates. Weekends, holidays, manufacturer production schedules, customization, payment review, carrier delays, weather, and freight appointment availability may affect delivery.

Custom clubs, cut shafts, assembled components, simulator screens, enclosures, studio packages, and other configured products may require additional production time. Please verify time-sensitive requirements with Grater Golf before ordering.

Order confirmation and tracking

An order-confirmation email confirms that we received your order; it does not guarantee availability or shipment. Tracking information is sent when it becomes available. For multi-item orders, tracking notices may arrive separately.

Address accuracy and delivery

Customers are responsible for providing a complete and accurate shipping address, telephone number, and email address. Contact us immediately if an address needs to be corrected. Once an order has entered fulfillment or shipped, an address change may be unavailable or may result in carrier fees.

Some high-value shipments require an adult signature. Once tracking shows delivery to the address provided, contact us promptly if you cannot locate the package. We will assist with available carrier procedures, but replacement or refund eligibility will depend on the carrier investigation and the circumstances of delivery.

Freight and oversized deliveries

We will inspect an authorized return after it reaches the designated return location. If approved, the refund will be issued to the original payment method for the eligible amount, less applicable restocking fees, return-label costs, nonrefundable shipping or freight, missing-item charges, and other disclosed deductions.

Please allow up to 10 business days after inspection for Grater Golf to process an approved refund. Your bank, card issuer, financing provider, or payment service may require additional time to post it. We do not control third-party posting times.

If the original payment method is unavailable or a refund cannot legally or technically be returned to it, we will work with you on an appropriate permitted alternative.

Exchanges

The fastest way to obtain a different eligible item is generally to complete an authorized return and place a new order. Do not send an item back until Grater Golf confirms whether an exchange or return-and-reorder process applies.

Defects and manufacturer warranties

Many products are covered by a manufacturer’s limited warranty. Warranty coverage, duration, registration requirements, exclusions, and remedies vary by manufacturer. A defect claim may be handled directly by the manufacturer or with assistance from Grater Golf.

Warranty coverage generally does not include normal wear, misuse, abuse, accidental damage, improper installation, failure to follow instructions, unauthorized modifications, cosmetic damage, commercial use where excluded, or damage caused by unsuitable room conditions, power, moisture, impact, or third-party equipment.

Contact us with your order number, serial number, description of the issue, troubleshooting already attempted, and clear photographs or video. Do not dispose of or return the product until instructed.

Simulator packages and split returns

A simulator package may contain products supplied by several manufacturers. Components may ship separately and may have different lead times, warranties, cancellation terms, and return eligibility. Returning one component does not automatically cancel or make the remaining package components returnable.

Package discounts, promotional items, financing terms, and bundled pricing may be recalculated if part of a package is returned. Any free or promotional item associated with a returned purchase must also be returned in new condition, or its retail value may be deducted from the refund.

Installation and room compatibility

Customers are responsible for verifying room dimensions, swing clearance, structural support, electrical capacity, mounting requirements, throw distance, screen size, aspect ratio, computer specifications, software compatibility, and compliance with applicable building or safety requirements before ordering or installation.

Builder recommendations and sales guidance are preliminary and depend on the measurements and information provided. Products are not returnable merely because a room, computer, network, mounting location, or third-party component does not meet published requirements when the product is otherwise correctly supplied.

Policy changes and consumer rights

We may update this policy from time to time. The version in effect when your order is placed will generally apply to that order, together with any product-specific terms disclosed during the sale.

Nothing in this policy limits rights or remedies that cannot be waived under applicable law.
