ALEX® IEC Standard Steel EMT Fittings (Couplings & Connectors)
STEEL
(Spanish Reference: CONECTORES Y COPLAS DE ACERO PARA TUBERÍA EMT)
Product Definition
ALEX® Steel EMT Fittings are the premium choice for electrical installations requiring superior mechanical strength and structural integrity. Unlike standard zinc die-cast fittings, these couplings and connectors are manufactured from high-grade tubular steel, making them virtually unbreakable under normal job site conditions.
Designed strictly according to IEC 61386 standards, they provide a secure, impact-resistant connection for EMT conduits in commercial and industrial environments where durability is prioritized over basic corrosion resistance.
Material Comparison: Why Choose Steel?
While Zinc Die-Cast is popular for general use, Steel is the superior choice for demanding indoor applications.

Key Features
Superior Durability: Capable of withstanding accidental hits from tools or equipment without cracking.
Space Efficient: The thin-wall steel construction offers a lower profile than bulky die-cast fittings, ideal for tight conduit racking.
Secure Grip: Hardened steel screws bite deeply into the conduit, ensuring excellent ground continuity.
Compliance: Meets international electrical safety codes (IEC 61386).
Frequently Asked Questions (FAQ)
Q: When should I use Steel instead of Zinc fittings?
A: Use Steel when the conduit runs are exposed to potential physical damage (e.g., warehouses, loading docks, exposed ceilings) or when you need the highest possible mechanical security. Use Zinc for standard concealed wall installations where cost is the primary factor.
Q: Are these fittings rust-proof?
A: Our steel fittings are Electro-Galvanized (Zinc Plated) to provide corrosion resistance suitable for indoor dry locations. For wet or corrosive outdoor environments, we recommend our specialized Liquid Tight or Hot-Dip Galvanized Rigid fittings.
Q: Do steel fittings fit standard IEC conduit?
A: Yes. They are precision-manufactured to fit all standard IEC 61386 metric EMT conduits (20mm to 110mm).
Q: Do you offer OEM branding?
A: Yes. We support OEM production. We can customize packaging (bags/boxes) and labeling to match your brand requirements.
Q: What is the lead time?
A: Our standard lead time is approximately 4 weeks. We recommend confirming specific delivery schedules with our sales team before placing large orders.
