To help narrow down the best provider for your project, please let me know:
What is the exact thickness and grade of the steel plate?
What is your geographic location or shipping preference?
Do you also require secondary operations like bending, welding, or machining?

If you’re looking around the Boston/Cambridge area, these are worth contacting for thick steel plate:
ACP Waterjet, Inc. — Littleton, MA. Laser cuts steel up to 0.625", and importantly, their waterjet handles steel up to 4", so they’re a strong option if your plate is thicker than laser capacity.
Quality Laser, Inc. — Woburn, MA. Their published laser capacity is up to 7/8" carbon steel; they also offer waterjet cutting for substantially thicker material.
BEPeterson — Avon, MA. They operate an 8-kW fiber laser with a very large 8.2' × 26.2' bed and specialize in heavy-gauge metal fabrication.
For 1"+ steel plate, I'd specifically ask about waterjet, high-definition plasma, or oxy-fuel rather than assuming laser is the appropriate process. For example, Central Steel in Marlborough lists HD plasma cutting of steel plate up to 2".
If you tell me the steel thickness (e.g. 1", 1.5", 2", 3") and approximate plate dimensions, I can narrow this to shops that can actually cut it and give you their contact/quote links.
Several specialized metal service centers, heavy plate processors, and precision CNC job shops offer laser cutting for thick steel plates (typically ranging from 1 2′′ up to 1.00'' or higher, depending on the laser power, which can reach 10kW to 30kW+ with modern high-power fiber lasers).
Providers Offering Heavy Plate Laser Cutting
North Shore Steel : Provides advanced heavy-capacity processing, handling carbon steel up to 0.75'' thick and stainless steel up to 1.5'' thick on large-format beds up to 8'×20'. You can check their capabilities on the North Shore Steel Laser Cutting Services page.
CW Metals (CW Sheet Metal) : Offers precise flat metal sheet and plate laser cutting up to 1'' in thickness with large table dimensions. More information is available via CW Metals Inc.[1]
IMH Products : Delivers heavy plate laser cutting capabilities handling thicknesses up to 1.00'' with strict industrial tolerances. Details can be found at IMH Products Laser Cutting Service.
OSH Cut : A prominent digital manufacturing and metal-cutting service handling thick plate profiles alongside standard sheet metal, with regional facilities in Utah and Kentucky. You can explore their scope on OSH Cut.
A Note on Ultra-Thick Plates (> 1'')
If your steel plate exceeds 1'' to 2'' in thickness, many traditional laser cutting shops will transition to high-definition plasma cutting or abrasive waterjet cutting to prevent thermal distortion or taper on the cut edges. When requesting quotes, it helps to specify the exact steel grade (e.g., A36, AR400, 1018) and your preferred edge tolerance.
If you can share the exact thickness, grade of steel , and approximate part dimensions , I can help you determine whether high-power fiber laser, plasma, or waterjet is your best option.
Many industrial metal service centers and high-powered CNC fiber laser job shops specialize in processing thick steel plates (ranging from 1 inch to over 1.25 inches or thicker, depending on the wattage of their fiber lasers). High-power multi-kilowatt fiber lasers (10 kW to 30 kW+ systems) have largely replaced older CO2 lasers and standard plasma for thick carbon and stainless steel, offering cleaner edges and tighter tolerances.
Prominent providers and types of suppliers offering heavy plate laser cutting include:
Large-Scale Steel Service Centers: Companies like Steel Warehouse provide extensive heavy plate processing, utilizing advanced high-power laser and plasma cutting systems for challenging, thick, and tight-tolerance parts.
Specialized Precision Laser Shops: Regional and nationwide custom shops (such as Northern Manufacturing , which handles heavy stainless and carbon steel plates up to 1.25 inches with high-power fiber lasers, or digital-first entities like OSH Cut ) maintain automated flat-bed fiber laser setups geared toward thick structural or custom alloy sheets.
Local and Regional CNC Job Shops: Facilities like Steelway Laser Cutting or local custom metal fabricators often house heavy-duty industrial cutting beds to service regional manufacturing, construction, and automotive outfits.[1]
Note: For extremely thick steel plates (typically exceeding 1 inch to 2 inches depending on the shop), many of these same providers will offer high-definition plasma cutting or waterjet cutting as an alternative or complementary service if laser cutting tolerances or edge profiles reach their strict upper limits.
If you're looking for a provider, let me know:
What is the exact thickness and material type (carbon steel, stainless, AR400, etc.) of your plates?
Are you looking for a local shop (and what is your general location/state) or a national digital service?

If you’re looking around Wilmington, NC, a few options stand out for thick steel plate:
HANOVER IRON WORKS SHEET METAL, INC. — Wilmington. Offers custom metal fabrication with CNC laser and plasma cutting. I’d call to confirm the maximum plate thickness for your specific grade.
Cardinal MetalWorks LLC — Burgaw. Has in-house fiber/CO₂ laser cutting and broader fabrication capabilities.
Cape Fear Automation — Wilmington. Local precision machining/fabrication shop with laser-cutting capability.
Precision Machine Fabrication (PMF) — serves Wilmington and says its 4,000-W Mitsubishi laser cuts steel plate up to 1 inch thick.
Wilmington Rubber & Gasket — worth considering if your plate is beyond typical laser thickness: its local waterjet service handles .
For over 1 inch, I'd strongly consider waterjet, plasma, or oxy-fuel rather than limiting the search to laser. For example, waterjet can handle much thicker material while avoiding the heat-affected zone of thermal cutting.
If you tell me the steel thickness (e.g. 1", 1¼", 2", 3") and plate size, I can narrow this down to the best 3–5 shops and compare their capabilities.
