Professional Structural Steel Rigging Services
Structural steel is the backbone of modern construction and fabrication—but moving beams weighing thousands of pounds, handling plate material measuring feet thick, and positioning massive trusses requires specialized rigging expertise that goes far beyond basic lifting skills. Alpha Rigging has spent 25+ years perfecting the art and science of structural steel rigging across Washington State.
Our OSHA-certified rigging crews understand that structural steel demands different handling techniques than other industrial materials. Steel components have unique balance points, require specific attachment methods to avoid damage, and often need to be maneuvered through tight fabrication shop spaces or precisely positioned at dizzying heights on construction sites. We bring the specialized equipment, engineering knowledge, and field-tested experience that keeps your steel—and your people—safe.
Why Structural Steel Requires Specialized Rigging
Unlike machinery with defined lift points or symmetrical loads, structural steel presents constantly changing rigging challenges. Each beam has a different center of gravity. Plates require specialized spreader systems to prevent bending. Long members need careful control to avoid dangerous swings. Our riggers have seen it all—and know how to handle it all.
What is Structural Steel Rigging?
Structural steel rigging is the specialized practice of safely lifting, moving, and positioning steel components used in building construction and metal fabrication. This encompasses everything from small angle iron to massive 100-foot bridge girders, requiring expertise in:
- Load Analysis: Calculating weight, determining center of gravity for asymmetrical members, and accounting for dynamic loads during movement
- Rigging Point Selection: Identifying safe attachment locations that prevent steel deformation, avoid damaging finishes or coatings, and provide balanced lifting
- Specialized Equipment: Using spreader bars to prevent sling crushing, employing beam clamps for direct attachment, and deploying custom rigging hardware for unusual shapes
- Movement Control: Managing long members that can swing dangerously, positioning steel with precision for welding or bolting, and working safely around personnel and structures
- Safety Protocols: Establishing exclusion zones beneath overhead steel, using tag lines for directional control, and maintaining constant awareness of changing load dynamics

Structural Steel Rigging Applications
Metal Fabrication Shop Support
Washington's metal fabrication industry depends on efficient steel handling. Our rigging services for fabrication shops include receiving steel deliveries and safely unloading from flatbed trucks, organizing steel inventory with overhead crane support or material handling equipment, positioning beams and plates for cutting, drilling, and welding operations, moving work-in-progress between workstations, and loading finished structural components for shipment. We work around your production schedule, understand the precision requirements of fabrication work, and can coordinate with your shop cranes or provide independent lifting capability.
Construction Site Steel Erection Support
Structural steel erection is one of construction's most hazardous activities. Our rigging support for construction projects includes unloading steel shipments at jobsites, rigging columns and beams for crane placement, providing iron workers with safe, stable loads for bolting and welding, handling specialty components like stair towers and architectural features, and coordinating with general contractors and steel erectors for seamless workflow. Our NCCCO-certified crane operators and OSHA-certified riggers ensure every lift meets safety standards and project timelines.
Steel Mill and Service Center Operations
Steel mills and service centers handle enormous volumes of structural products daily. We provide rigging services including rail car unloading with heavy-capacity equipment, inventory management and warehouse organization, customer order preparation and loading, scrap steel handling and recycling operations, and maintenance support for mill equipment and infrastructure. Our teams understand the pace of steel distribution operations and work efficiently to minimize disruption.
Bridge and Infrastructure Projects
Washington's aging infrastructure requires constant maintenance and replacement. Alpha Rigging supports bridge and highway projects with specialized rigging for massive bridge girders—some weighing over 100 tons, complex lifts over water or active roadways requiring detailed planning, night work to minimize traffic impact, coordination with WSDOT and transportation authorities, and emergency response for accident damage or structural failures.
Our Structural Steel Rigging Process
Step 1: Steel Assessment & Load Analysis
Before touching any steel, we analyze the components: actual weights (steel is heavy—we verify instead of assuming), center of gravity locations for asymmetrical members, steel grade and strength for attachment point planning, protective coating requirements (galvanized, painted, etc.), and environmental factors like wind exposure. This analysis informs every subsequent rigging decision.
Step 2: Rigging Design & Equipment Selection
Based on our analysis, we design the optimal rigging configuration: sling size, type (wire rope, synthetic, chain), and placement, spreader bar requirements to prevent load crushing or sling damage, beam clamps or other attachment hardware for direct connection, crane selection and positioning for optimal lift geometry, and tag line placement for load control during movement. All rigging equipment is inspected and load-rated per OSHA requirements.
Step 3: Site Preparation & Safety Setup
Safety is established before any lifting begins: exclusion zones are marked beneath all overhead work, personnel are briefed on lift sequence and hazards, communication protocols are established (hand signals, two-way radio), emergency procedures are reviewed with all crew members, and environmental conditions are monitored (wind speed is critical for long steel members). Only when safety is confirmed do we proceed.
Step 4: Rigging and Initial Lift
Our certified riggers attach rigging hardware to predetermined points, verify all connections are properly seated and secured, attach tag lines for directional control when needed, and perform a test lift—raising the load just inches to verify balance and rigging integrity. This test lift is mandatory and has prevented countless accidents by catching rigging issues before loads reach dangerous heights.
Step 5: Controlled Movement & Positioning
With rigging verified, we execute the planned move: smooth, controlled lifting without shock loading, tag line management to prevent dangerous swinging, constant communication between operator, riggers, and spotters, clearance verification throughout the entire move path, and precision positioning for final placement. Long steel members require special attention—a 60-foot beam acts like a pendulum if not properly controlled.
Step 6: Secure Placement & Rigging Removal
Once positioned, steel is secured before rigging removal: blocking, cribbing, or temporary support is installed, welders or iron workers are given access for permanent attachment, rigging hardware is safely removed only after load is secured, and all rigging equipment is inspected post-lift for wear or damage. Every component is documented and returned to service only if it passes inspection.
Specialized Rigging Equipment for Structural Steel

Frequently Asked Questions: Structural Steel Rigging
A: We use engineering calculations based on member dimensions and steel density (490 lbs/cubic foot for steel) to locate the center of gravity. For complex shapes or members with holes, cutouts, or attachments, we may use CAD software or perform test lifts to verify balance. Proper balance is critical—an off-center pick can cause dangerous tilting or load shifting.
A: Yes. We use synthetic slings (nylon or polyester) that won't scratch coatings. For direct attachment, we use soft protective pads at contact points. Beam clamps can be used on flanges where small marks are acceptable, or we design rigging that attaches at areas that will be covered by connections. Protecting your finish is part of our standard service.
A: We regularly handle beams up to 90 feet in length. Longer members (100+ feet) are possible with specialized equipment and planning. Length presents challenges beyond just weight—long beams have significant wind loading, require large radius crane work, and need careful control to prevent dangerous oscillation. We've successfully moved bridge girders exceeding 120 feet.
A: Yes. We work alongside iron workers and steel erectors providing professional rigging services. This includes setting columns, placing beams, handling joists and decking, and specialty items like stair towers. We coordinate with the erection crew's schedule and work methods to ensure safe, efficient steel placement.
A: Absolutely. Many fabrication shops have 20-30 foot ceilings that limit crane boom height. We use hydraulic gantry systems that provide substantial capacity in low-headroom environments, telescoping boom cranes with minimal height requirements, and heavy-duty forklifts with boom attachments for flexibility. We'll assess your shop and recommend the best approach.
A: Yes. Many fabrication shops schedule us for regular steel deliveries, periodic material handling support, or on-call service when they need rigging beyond their shop crane capacity. We can establish scheduled service agreements with preferred pricing for regular customers. This ensures equipment and crew availability when you need us.
A: For most steel rigging, we work up to 20 mph sustained winds. Long, tall members (like columns or long beams) may have lower limits—as low as 15 mph for extremely large surface areas. Bridge girders and other massive components often have engineered wind speed limits. We monitor conditions continuously and stop work if winds exceed safe limits.
A: Yes. We provide rigging services for scrap operations including sorting and organizing scrap inventory, loading scrap for shipment to recyclers, handling cut-up structural members from demolition, and organizing scrap bins and storage areas. Scrap steel is often awkward and tangled—we have the experience to handle it safely.
A: Yes. While most structural steel is mild carbon steel, we regularly handle stainless steel (requiring extra care to prevent scratching and contamination), high-strength alloys (requiring verification of material strength for attachment calculations), and weathering steel (Cor-Ten). We adjust our rigging methods and protective measures based on material properties and customer requirements.
A: For routine steel handling (unloading deliveries, shop moves, standard construction lifts), 3-5 business days ensures crew and equipment availability. Complex lifts requiring engineering analysis or specialty equipment need 1-2 weeks. Emergency response is available 24/6 with typical mobilization in 24-48 hours. For major projects, contact us during planning stages—early involvement often identifies cost savings and efficiency improvements.
