Argentina’s energy transition is advancing through large-scale projects that position the country as a relevant player in renewable energy at the regional level. Parque Solar El Quemado is one of the most compelling examples of that process. At Chousa, we […]
Electrical infrastructure operates continuously under demanding environmental conditions. Transmission lines, substations, transformers and towers are exposed to permanent humidity, rain, industrial contamination, UV radiation and constant thermal cycling. In that environment, the components that support and connect that infrastructure — […]
The retention clip is the most overlooked component in a braking system. It is also one of the most critical — especially in the automotive aftermarket, where the variety of applications and operational demands makes selecting the right coating a […]
A325 bolts are at the core of thousands of metal structures. But many fail prematurely — and almost always for the same reason: the wrong coating. What are A325 bolts and where are they used? A325 bolts are […]
A grade 12.9 bolt passes every quality control, is correctly installed, and fails within 72 hours. No visible corrosion. No overload. The problem occurred before assembly, during the coating process. It’s called hydrogen embrittlement, and in the metalworking industry it’s […]
The problem with 12.9 bolts in seed drills In seed drills, 12.9 bolts operate under highly demanding conditions: constant vibration from field operation, dynamic loads, and continuous exposure to moisture, fertilizers, and accumulated dirt. These conditions place 12.9 bolts in […]
Corrosion is often perceived as a technical issue. But in reality, it is an economic problem. Every corroded component not only represents material damage, but also a series of associated costs that directly impact operational profitability. In many industries, the […]
In the Oil & Gas industry, bolted joints are critical to the integrity of equipment and process systems. Flanges, valves, and pressure vessels rely on the reliability of these fasteners to operate safely over long periods of time. One of […]
In solar power plants, trackers are among the most mechanically demanding systems. They incorporate continuous movement, variable loads, and repetitive cycles throughout the entire service life of the project. In this context, fasteners play a central role in the operation […]
In machinery exports, one of the most frequent—and costly—issues is premature corrosion in exported machinery. Fasteners, bolted joints, structures, and metal subassemblies begin to show corrosion shortly after delivery or during the early stages of operation. These failures are rarely […]
