Industrial chain is chain rated for one kind of job, whether binding, towing, hauling, or overhead lifting. A chain that secures equipment on a flatbed is not automatically fit to lift it. St. Pierre Chain & Wire Rope supplies Grade 30, 43, 70, 80, and 100 chain and stainless steel chain to Boston, MA contractors, trucking fleets, utilities, towing companies, and marine operators from our Worcester, MA facility.
We also fabricate alloy chain slings and custom chain assemblies and proof test them in house. St. Pierre has been family-owned since 1920. Call (800) 926-2342 or (508) 853-8010, or email Orders@stpierreusa.com, to confirm current availability.
Which Industrial Chain Grade Fits the Job?
Grade alone does not set capacity. Size, configuration, sling angle, temperature, and condition all matter, and the marked working load limit always governs.
Grade 30 Proof Coil Chain
Low-carbon, economical chain for barriers, fencing, light pulling, and utility work. Available in multiple finishes and custom lengths. Not for overhead lifting.
Grade 43 High-Test Chain
More strength than Grade 30 for towing and recovery, logging, and agricultural equipment, without the cost of alloy chain. Not for overhead lifting.
Grade 70 Transport Chain
Heat-treated carbon steel, often gold-colored, for cargo securement, load binding, tiedowns, and towing. Its working load limit is higher than Grade 30 of the same size. DOT-compliant, and not for overhead lifting. We also supply the rated binders to go with it.
Grade 80 Alloy Lifting Chain
Heat-treated alloy chain used in overhead lifting slings across construction, fabrication, maintenance, and manufacturing. For lifting, it must be built into a designed, identified, and inspected sling with load-rated components.
Grade 100 Alloy Lifting Chain
Roughly 25% more working load capacity than Grade 80 of the same nominal size. That lets a lighter sling carry the same load, or adds capacity without moving up a chain diameter. The finished sling is rated by its weakest component.
Stainless Steel Chain
For wet, corrosive, and high-sanitation settings: marine and offshore work, coastal construction, food and beverage processing, and chemical wash-down areas.
Replacing an existing chain? Do not go by link diameter or color. Confirm the grade, manufacturer marking, working load limit, and condition. Pull chain with missing identification, wear, stretch, cracks, deformation, severe corrosion, heat damage, cuts, or gouges until a qualified person evaluates it.
Chain Slings and Custom Assemblies Fabricated in Worcester
A chain sling is a complete lifting system, and a lower-rated component drags down the whole assembly. We fabricate alloy chain slings at our Worcester, MA facility using load-rated fittings from Columbus McKinnon and The Crosby Group, in configurations that include:
- Single-leg slings for vertical and straight-line lifts
- Double-, triple-, and quad-leg bridle slings for loads with multiple lift points
- Basket and choker configurations where the load allows
- Adjustable assemblies with approved shortening devices
- Grab, sling, or foundry hooks and other rated end fittings
- Custom assemblies for lifting, securement, towing, and material handling
Angle matters on multi-leg slings. Tension on each leg climbs as it moves away from vertical, so we select by the actual lift geometry, not by dividing the load weight by the number of legs.
Proof Testing and Documentation
We proof test chain, wire rope, and rigging assemblies in house up to 100,000 pounds, which saves the delay of sending work to an outside lab. Proof-test certificates are available on request. Give us the test load, the standard or customer specification, and your documentation needs when you ask for a quote.
Industries Using Industrial Chain in Boston
Steel fabricators and construction crews lift machinery and precast with alloy slings. Plants lift dies, motors, and pumps. Trucking fleets secure cargo with Grade 70 and rated binders. Utilities, towing companies, marine operators, and warehouses each get chain matched to the load and the environment.
How to Order Industrial Chain From St. Pierre
Step 1: Describe the Job
Tell us if the chain is for overhead lifting, cargo securement, towing, or pulling. For a lifting sling, bring the load weight including fixtures, lift point count and location, number of legs, reach, expected sling angle, crane hook or hoist dimensions, hook throat opening, and exposure to heat, chemicals, sharp edges, moisture, or abrasion.
Step 2: Request a Quote
Email Orders@stpierreusa.com or call
(800) 926-2342. We review the use, grade, size, configuration, and fittings, then confirm pricing, availability, and lead time. For a replacement sling, photos of the tag and end fittings help but do not replace accurate load and dimension data.
Step 3: Approve and Receive
We fabricate and test the assembly, then prepare it for pickup, delivery, or shipment depending on the order and destination. Test documentation comes with the order.
Why Boston Businesses Choose St. Pierre for Industrial Chain
- Family-owned since 1920: we started with tire chains, then moved into forged products and industrial rigging.
- Navy-recognized: during World War II we produced aircraft parts and anchor chain and earned the U.S. Navy “E” for Excellence.
- Matched hardware: shackles, grab hooks, sling hooks, master links, swivels, and coupling components from Columbus McKinnon and The Crosby Group.
- One supplier for the whole lift: wire rope, wire rope and synthetic slings, hoists, eyebolts, and turnbuckles, so chain and fittings are not mismatched.
- Easy to get: local pickup, delivery, or shipping, with chain in multiple grades and sizes subject to current stock.
Frequently Asked Questions About Industrial Chains in Boston, MA
What is the difference between Grade 80 and Grade 100 chain?
Grade 100 carries about 25% more working load than Grade 80 of the same nominal size. Both are alloy grades for overhead lifting slings, and every component in the sling must be compatible and properly rated.
Can Grade 70 chain be used for overhead lifting?
No. Grade 70 is transport chain for securement, binding, and towing. Overhead lifting requires alloy chain and rated components assembled and inspected as a lifting sling.
Does St. Pierre supply chain to Boston-area customers?
Yes. We supply chain, slings, and rigging hardware to Boston from our Worcester facility, with pickup, delivery, or shipping depending on the order. Call
(800) 926-2342 or email Orders@stpierreusa.com for availability and lead time.
Can St. Pierre build a custom sling and proof test it?
Yes to both. We fabricate single- and multi-leg alloy slings and custom assemblies in Worcester, and we proof test in-house up to 100,000 pounds. Tell us the load, reach, legs, angle, and test requirements so we can confirm the test is within our capability.
