View SpecificationsSão Paulo represents the economic engine of Brazil and South America. The metropolitan area, along with satellite industrial hubs such as Campinas, Sorocaba, and the ABC region, demands millions of metric tons of structural steel annually. High-performance Rectangular Steel Tubes are central to this growth, acting as the structural skeletal framework for large-scale warehouses, automotive production facilities, commercial high-rises, and major logistics terminals connecting to the Port of Santos.
Local procurement directors are increasingly moving away from domestic supply bottlenecks to secure reliable import pipelines. Our certified rectangular profiles align with the exact requirements of Brazilian contractors, satisfying both national engineering traditions and modern eco-friendly development mandates.
Helping international EPC firms, Brazilian distributors, and Tier-1 construction contractors manage import risks and maintain quality standards.
We produce in strict conformity with ASTM A500, EN 10219, and JIS G3466. Our manufacturing operations comply with Brazilian NBR 8261 structural profiles, securing rapid approval from onsite inspection teams.
Leveraging direct export pathways from China, we coordinate ocean freight shipments arriving at the Port of Santos. We supply standard breakbulk or containerized shipments with anti-corrosive packing and clear documentation.
Importing steel into Brazil requires careful fiscal planning. We provide transparent invoicing, certificates of origin, and bill of lading documents to streamline the Desembaraço Aduaneiro (customs clearance) process.

View SpecificationsHow we ensure every rectangular steel tube shipped to Brazil complies with complex engineering specifications.
Every batch undergoes rigorous weld seam inspections. Using electromagnetic and ultrasonic testing (UT) equipment, we detect micro-fissures or weld gaps, ensuring the tube wall exhibits seamless performance under heavy stress loads.
Using state-of-the-art cold-forming sizing blocks, we maintain corner radii and wall thickness tolerances within the tight margins defined by ASTM A500. This minimizes assembly issues and speeds up onsite welding in São Paulo.
All shipments are accompanied by Mill Test Certificates (MTC) according to EN 10204 Type 3.1. Chemical compositions (Carbon Equivalent values) and mechanical metrics are documented to simplify compliance audits.
Answers to common questions from Brazilian engineers and procurement specialists regarding imported structural tubing.
Yes. The Brazilian NBR 8261 standard closely follows the technical specifications of ASTM A500. We select corresponding carbon steel grades and structural dimension criteria to satisfy both standards, ensuring structural plans are approved by municipal inspectors in São Paulo.
Manufacturing typically takes 20 to 30 days depending on the volume and customization. Ocean freight from China to the Port of Santos averages 35 to 45 days. We work closely with major shipping lines to coordinate reliable container drop-offs and minimize port delays.
Absolutely. Our advanced sizing lines enable custom adjustments to wall thicknesses ranging from 2.0mm to 16mm, and lengths can be cut to custom sizes (e.g., 5.8m to fit standard shipping containers, or up to 12m for bulk vessels) to reduce material waste at the job site.
We employ multiple layers of transit protection, including light oiling, plastic end caps, and heavy-duty waterproof geotextile wrapping. For maximum protection, hot-dip galvanized coating offers robust defense against humid ocean air.
