Brackets, flanges, fastening parts and mechanical components custom-machined for onshore wind towers. Production capacity at scale.
Request a Quote WhatsAppBuilding and maintaining wind towers requires mechanical components machined with precision and at scale — a single tower has dozens of custom parts along its 80-150 meters of height. Gromar meets that demand by manufacturing flanges, brackets, fastening parts, internal elevator components and access cone items.
We work with tower manufacturers, turbine OEMs and O&M companies that need fast replacement at wind farms. Capacity to serve programs with recurring volumes and proprietary technical drawings.

Processes certified to ABNT NBR ISO 9001:2015 — audited quality in every batch.
Manufacturing industrial parts and equipment since 1986 with multi-sector expertise.
Work from technical drawings or reverse engineering, tailored to your equipment.
Shorter lead time than OEM imports for many components, with technical support from Brazil.
We manufacture joining flanges between tower sections, internal elevator and cable brackets, nacelle access cone parts, fastening components and preventive/corrective maintenance items. We work with structural carbon steels, alloy steels and stainless steels according to the part's exposure, with treatments such as galvanizing, industrial painting or quenching defined by the customer's project.
Yes, within our production capacity. We serve everything from single replacement batches to recurring production of components at scale for tower manufacturers. For large-dimension parts — such as tower section flanges — we ask for the technical drawing in advance, to confirm machine capacity, available treatments and suitable shipping logistics.
Yes. We work both with tower manufacturers and turbine OEMs and with O&M (operation and maintenance) companies that need fast replacement at wind farms spread across Brazil. We structure contracts with recurring volumes, strategic stock parts and defined lead times, aligned with each customer's preventive and corrective maintenance cycles.
Our machining is certified to ABNT NBR ISO 9001:2015, as stated in the product data sheet. This guarantees audited quality in every batch, material traceability, documented dimensional control and conformity of the applied heat and surface treatments — industrial painting, galvanizing and quenching among the most used in wind tower components.
Yes. We serve wind farms, tower manufacturers and O&M companies throughout Brazil. Machining is done in Piracicaba/SP and shipping is handled by carriers specialized in industrial freight, with priority dispatch for urgent cases. We also serve international companies — contact our sales team to arrange logistics.
