How Chengrui Empowered a Brazilian Trader to Revolutionize His Insulation Supply Chain‌

‌Client Profile‌

Marcos Oliveira, a seasoned entrepreneur from Curitiba, Brazil, founded ElétricaSafe in 2010 to distribute industrial insulation materials. His company served automotive workshops, solar panel installers and HVAC 

contractors across southern Brazil. While Marcos built a loyal client base, scaling the business became a struggle. Local fiberglass sleeving suppliers frequently shipped products with frayed edges or inadequate heat resistance (max 150°C), forcing him to reject 15%. of orders. European imports offered better consistency but ate into profits due to tariffs and 10-week shipping times.

‌

The Breaking Point‌

In late 2022, a major client—a car parts manufacturer in Porto Alegre canceled a recurring order after ElétricaSafe delivered fiberglass sleeves that cracked during engine heat tests. Marcos faced a dilemma: continue compromising on quality with local vendors or sacrifice margins with overpriced imports. A supplier audit revealed another issue: Brazilian producers lacked certification for international safety standards, limiting his ability to bid on government infrastructure tenders.

Discovering Chengrui at EXPOSUCATA‌

Determined to find a solution, Marcos attended EXPOSUCATA 2023, São Paulo’s largest trade fair for industrial materials. At Chengrui’s booth, sales manager Jessica demonstrated sleeving samples woven with high-density fiberglass and coated with flame-retardant silicone. What caught Marcos’ eye was the product’s 220°C thermal endurance rating—a necessity for Brazil’s automotive and solar sectors. Jessica explained how Chengrui’s vertical integration from raw material processing to braiding machines allowed cost efficiencies European brands couldn’t match.‌

Testing the Waters‌

Skeptical but curious, Marcos ordered 200 meters of 10mm sleeving for real-world testing. Chengrui’s engineers customized the sleeve thickness to withstand Brazil’s humid coastal environments, a persistent pain point with his previous suppliers. Within 12 days, the shipment arrived via Chengrui’s logistics partner, avoiding Santos Port’s notorious congestion. Field tests with a compressor manufacturer in Joinville showed zero sleeve degradation after 500 hours of continuous use, exceeding client expectations.‌

Cost and Quality Breakthrough‌

Chengrui’s pricing model sealed the deal. By eliminating intermediaries, Marcos secured sleeves at BRL 18.50/meter, 28%. cheaper than German equivalents. Even after import taxes, his margins improved by 13%. The clincher was Chengrui’s ISO 9001 and IEC 60684-2 certifications, which enabled Marcos to qualify for a R$2.3 million tender supplying Brazil’s Northeast wind farm project.‌

Operational Transformation‌

Within 8 months, Marcos shifted 85%. of his fiberglass orders to Chengrui. The manufacturer’s 10-day turnaround for repeat orders vs. 6 weeks from Europe let him reduce warehouse stock costs, freeing up capital. Chengrui’s bilingual QC reports also resolved a chronic issue: Brazilian customs often delayed shipments due to incomplete documentation.‌

Client Testimonial‌

“Chengrui didn’t just sell us sleeves, they became a strategic partner,” Marcos noted. “Their engineers even helped us develop a double-layer sleeving kit for electric vehicle battery lines, which is now our top-selling product.”‌

Conclusion‌

Marcos Oliveira’s journey underscores how Brazilian traders can overcome supply chain bottlenecks by partnering with agile, quality-driven manufacturers like Chengrui. By combining rigorous testing, localized customization, and lean pricing, Chengrui continues to redefine South America’s insulation material landscape.
