Custom Wind Turbine Tower Internals | Turbine Platforms and Ladders
Wind Power presents a sustainable source of energy that has several advantages over conventional forms of energy. Wind Turbine Tower Internals are components within a wind tower that provide access throughout the structure and facilitate its maintenance. Tower internals can include platforms, hatches, ladders, stairways, and doors, and are a key factor in successful turbine operation.
We have been supplying various wind turbine tower internals and internal kits and assemblies for industry leaders such as GE Power, ENERCON, Acciona, TSP, and UNISON. The decades of laser-cutting fabrication and flexible manufacturing capabilities allow fulfilling custom tower platforms, stairways, and hatches with higher precision, short lead times, and a longer lifespan.
Wind Turbine Tower Platforms
Wind Turbine Tower Platforms placed throughout the height of the tower are crucial for the successful maintenance of the turbines. LPR Global supplies both steel and aluminum platforms for wind turbine towers of various sizes.
Clients benefit from in-house design capabilities for various top and bottom platform sizes, which are continuously developing through years of specialization in wind turbine towers. In addition, the platform internals for the top and bottom of the tower are easy to identify for assembly. Our wind turbine platforms are used for wind turbine towers from GE Power, ENERCON, and Acciona.
GE Power Wind Turbine Platform Parts
We have been a long-term supplier to GE’s Directed Buy Program for wind turbine internal components, including ladder brackets, platforms, and stairways. We have supplied for numerous projects for GE Power, including 1.6 MW-rated turbines with 80 m blade diameters.

ENERCON Wind Turbine Platform Components
ENERCON, a German manufacturer and market leader, is another long-term client of ours; they are being supplied parts for various assemblies in models such as the E-82 and E-92 wind turbines, with both having a rating of up to 2.3 MW. ENERCON turbines have been used in a range of design scenarios, attesting to the high standards of LPR Global’s products.
Wind Turbine Tower Ladders
Wind Turbine Tower Ladders for access to various tower platforms are also custom manufactured with steel or aluminum alloys. The high-quality laser cutting machines can manufacture ladder internals with short lead times.

Non-Destructive Testing for Quality Assurance & Quality Control
To guarantee robust and durable wind turbine internals and other machined components, LPR Global utilizes a variety of non-destructive testing (NDT) methods to check for defects. These methods include ultrasonic testing for flaws in the material, penetrate inspection to check for surface-breaking defects, and magnetic particle inspection to detect discontinuities in metals.
Custom Metal Fabrication for Frames of Agricultural and Construction Equipment
LPR Global’s large-sized fabrication and machining shop has a comprehensive range of fabrication and machining capabilities for various components of industrial machine frames, Heat Recovery Steam Generator (HRSG) Plants, heavy equipment parts for agricultural or construction purposes, and wind turbine tower internals.
We started using laser cutting for precision sheet metal fabrication ever since it was introduced to the fabrication and machining market. The early adoption of laser cutting machines in fabrication facilities allowed shorter fabrication processes as well as better cycle times and quality. We identified correctional machining work after the conventional machining process as a big cost in production and counter-productive for cycle time. The minimized after-machining work and shortened production time ultimately provide great prices and excellent quality to clients that request customized precision laser cutting services for their projects. Currently, laser cutting fabrication and machining services are processed by Bystronic, Tanaka, and Trumpf lasers, which perform high levels of precision.
Our clientele for laser cutting fabrication services exemplifies the high precision quality and decades of fabrication and machining experience with varying metal types (steel, stainless steel, aluminum) used in different industries. Some examples of current clients are IHI and MHI in Japan, who use our laser-cut metal parts for their HRSG plants. For heavy equipment used for agriculture and construction, fabricated machine frames and metal parts are manufactured.
The precision laser cutting fabrication service proudly possesses 5 patents in South Korea. Not to mention that the Quality Management System has been certified to the standard of ISO 9001:2015, which implies a high degree of quality assurance and quality control maintenance.
Precision Laser Cutting and Drilling Services for Heavy Equipment Frames
LPR Global’s large-sized fabrication shop specializes in precision laser cutting services. The laser cutting service provides solutions to precision sheet metal cutting and drilling services for sheet metals with thicknesses ranging from 1mm to 25mm. Such thickness is the most popular size range of sheet metals used for machine frames of agricultural equipment and heavy construction equipment. Our clients for precision laser cutting fabrication and machining services include manufacturers of agricultural equipment and construction equipment (e.g., excavators).

Welding Quality Control
LPR Global’s extensive welding capabilities are used for extremely robust welded components for Agricultural Equipment, Construction Equipment and Heat Recovery Steam Generator (HRSG) plants.
LPR Global maintains a high level of welding quality control with our in-house inspection and testing process. We begin with an initial assessment of the raw materials. Then, a visual inspection of workmanship is conducted for each welded component, including inspection of the outer and back beads.
Welding Inspection Procedure
- Prior to welding, the drawings, welding process standards, and the Process Quality Report checklist are checked to confirm the work to be performed. Furthermore, the license of the welder, the welding equipment and tooling are inspected as work begins.
- During the welding process, the cleanness of the interlayers, adherence to welding procedures, the interlayer temperature and the air flow through the workspace are monitored to ensure a stable welding process. The adequacy of tack welds and the width of weave beads are constantly checked to certify that the weld will be as specified. This ensures that defects such as arc strikes, crater cracks, uneven beads, and the deformation of unwelded areas do not occur.
- After welding is complete, we inspect the bead height, width, and depth, as well as check for surface defects, weld slag or weld splatter, arc strikes and post welding heat treatment to ensure that the weld is free of deficiencies.
HRSG Project References
We specialize in producing custom components for HRSG Harps, such as baffle plates, lug plates, end plates, and HRSG drums. Our laser machining capabilities are especially suited for the high precision required by these internals.
Our HRSG clients include Doosan Construction, Doosan Engineering, IHI, and BHI for Heat Recovery Steam Generator Components for heat recovery boilers.
Hot Dip Galvanizing
Hot Dip Galvanizing, also known as zinc galvanizing or zinc dipping, ensures that our products are highly corrosion resistant. LPR Global performs in-house hot galvanizing to eliminate burning, zinc pimples, dark staining or storage staining, which commonly impact ungalvanized or poorly galvanized surfaces. Industrial Hot Dip Galvanizing ensures that our wind tower internals are robust and have excellent anti-corrosion protection.
Our in-house zinc coating also provides a lustrous finish and reduces impurities while providing anti-corrosion properties to our custom components.
Hot dip galvanizing finishes are thoroughly inspected to guarantee quality before shipment to our clients. We ensure that our zinc dipped fabricated products meet ISO:1461 standards, a standard for hot dip galvanizing coatings on iron and steel.
Conventional Fabrication and Machining Services
In addition to our specialized laser cutting machine capabilities, we also have in-house expertise in conventional machining techniques such as industrial cutting, pressing, milling and grinding. Our capabilities have been used in fabrication for heavy industry, power plant facilities, and other steel structures such as parking facilities.
