Spider Fittings for Facades Mexico: Seismic Safety & 3D Guide
Introduction: The Transparent Skyline of CDMX
From the towering corporate skyscrapers of Santa Fe to the luxury boutiques of Polanco and the historic renovations in Centro Histórico, Mexico City (CDMX) is undergoing a transparent revolution. Modern Mexican architects are increasingly favoring expansive glass facades to invite natural light and create a sense of openness.
However, building in the Valley of Mexico presents a unique challenge known to every local engineer: Seismic Activity.
How do you balance the minimalist beauty of a "floating" glass wall with the structural safety required in an active earthquake zone? The answer lies in selecting the correct connection technology.
In this comprehensive guide, we will explore the mechanics of Stainless Steel Spider Fittings and Routels, demonstrated by our latest 3D animation, and explain why they are the preferred choice for safety-conscious projects in the State of Mexico and surrounding industrial hubs like Toluca and Puebla.
Part 1: Visualizing the Mechanics (3D Animation)
Before diving into the technical specifications, it is crucial to understand how these components interact with the glass and the steel structure.
We have created a detailed 3D animation to demonstrate the installation process of our Point-Fixed System. This video highlights the precision engineering required to secure heavy glass panels safely.

As you can see in the video, this system is not just a rigid fixation; it is an articulated mechanical system designed for movement and load transfer.
Part 2: The Core Components of the System
A point-fixed glass curtain wall relies on two primary stainless steel components. These are the heroes of our product line:
1. The Spider Fitting (Herrajes Tipo Araña)
This is the structural claw that connects the glass to the supporting structure (whether it be steel columns, cables, or glass fins).
Function: It acts as the load-bearing anchor. Available in 1, 2, 3, or 4-arm configurations depending on the glass positioning (corner or center).

As shown in the animation, the Routel is the bolt assembly that passes through the pre-drilled holes in the glass.
Function: It connects the glass to the Spider arm. Crucially, high-quality routels include a "ball-joint" mechanism that allows the glass to swivel slightly under pressure.

When sourcing architectural hardware for projects in Mexico, aesthetics is secondary to safety. This is where our products stand out against rigid frame systems.
The Principle of "Flexible Articulation"
In a traditional framed window, the glass is tightly held in a rigid frame. When an earthquake hits CDMX, the building sways. If the frame distorts, it squeezes the glass, causing it to shatter.
Why Spider Fittings are Safer:
Our Spider and Routel system functions like a joint (articulation).
Stress Absorption: When the main steel structure moves during a tremor (inter-story drift), the ball-head mechanism in our Spider Routels allows the glass panels to rotate and tilt slightly rather than resisting the force.
floating Effect: The glass is essentially "suspended," preventing the transfer of structural deformation directly to the fragile glass pane.
For high-rise buildings on Paseo de la Reforma, this flexibility is not a luxury—it is a necessity for compliance with rigorous safety codes.
Material Grade: Fighting Pollution and Rain
Mexico City is a bustling metropolis, and with that comes urban pollution and distinct rainy seasons.
We strongly recommend AISI 316 Grade Stainless Steel for all exterior facades in the region.
Unlike standard 304 steel, Grade 316 contains Molybdenum, offering superior resistance to pitting and corrosion caused by acid rain and urban pollutants. This ensures your facade remains gleaming for decades without the ugly streaks of rust.
For contractors and glaziers working on-site, here is a breakdown of the installation logic shown in our video:
1.Steel Preparation: The connector base is welded or bolted to the main steel beam. Precision here is key to ensuring the facade is plumb.
2.Routel Assembly: As seen in the clip, the Routel body is inserted through the countersunk or flat hole in the glass.
3.Gasket Protection: Crucial Step — Ensure the fiber or nylon gaskets (shown in black in the video) are correctly placed. Metal should never touch glass directly.
4.Mounting: The glass panel, with routels attached, is lifted and aligned with the Spider Fitting arms.
5.Securing and Adjustment: The cap nuts are tightened. Our system allows for minor in-and-out adjustments to compensate for steel tolerances, ensuring a perfectly flat glass surface.
Where can you utilize this technology?
Automotive Showrooms: Brands like Audi or Mercedes often use our point-fixed systems to create invisible barriers that highlight the cars inside.
Shopping Mall Atriums: Ideal for skylights and entrances in plazas like Centro Santa Fe or Perisur, maximizing daylight entry.
Double-Skin Facades: For energy efficiency in corporate towers, creating a thermal buffer zone using a second layer of spider-fixed glass.
Whether you are designing a boutique hotel in Roma Norte or an industrial complex in Querétaro, the hardware you choose defines the longevity and safety of your facade.
Don't compromise on the structural integrity of your glass walls. Choose stainless steel fittings that are engineered for performance.
