America's Border Wall Is a Massive Steel Manufacturing Challenge. Here's How They Build It

How does America build a border wall with roughly 6,000 steel posts per mile? This engineering documentary follows the manufacturing processes behind 30-foot steel bollards, from massive steel coils, precision slitting and plate stretching to tube forming, welding, CNC drilling, laser cutting and robotic assembly. Discover how industrial machines turn days of manual steelwork into minutes—including a 560-hole beam drilled in just 58 minutes. See shot blasting, weld inspection, magnetic lifting and heavy steel transport before cranes install towering panels across Arizona's desert and the steep terrain near San Diego. The video also explores the trade-offs between physical barriers, surveillance technology and the cost of border security. See why precision matters when every post must fit.
