Simpson Straps & Ties

Simpson Straps & Ties: Essential Structural Connectors for Professional Construction

When you're building structures that need to withstand wind loads, seismic forces, and heavy structural demands, Simpson Strong-Tie's comprehensive line of straps and ties delivers the engineered connections you can count on. These load-rated connectors are designed to meet specific code requirements while providing reliable field performance across residential, commercial, and heavy construction applications.

Flexible Strap Solutions

Simpson Coiled Straps (CS, CSHP, CMST Series) offer field-adjustable length for custom applications. The CS models function as continuous utility straps that can be cut to exact job requirements, eliminating waste and providing installation flexibility. The CMST series features pre-punched nail slots for faster installation, while the CSHP provides higher load capacity for demanding connections.

Seismic and Hurricane Protection

Simpson H and TSP Series Seismic & Hurricane Ties create critical connections between rafters, trusses, and wall plates to resist lateral forces. These ties are essential for meeting wind and seismic design requirements, particularly in high-wind zones and seismically active regions. The H series offers multiple configurations for different load requirements, while TSP models provide enhanced performance for demanding applications.

Rigid Connection Systems

Simpson Rigid Tie Connectors (RTC and FWH Series) establish solid 90-degree connections between wood members and vertical posts. The RTC42 and RTC44 models handle heavy structural loads, making them ideal for beam-to-post connections in commercial framing. The FWH four-way connector works specifically with 2x lumber for residential and light commercial applications.

Standard and Heavy-Duty Strap Ties

Simpson LSTA, ST, and HRS Strap Ties provide versatile tension connections for 2x lumber applications. These ties feature engineered nail patterns that minimize splitting while maximizing holding power. They're commonly used for floor-to-floor connections and general structural tie applications.

Simpson Strap Ties MSTA, MSTC, and MSTI Series step up to heavy-duty applications with increased thickness and fastener capacity. These high-strength ties handle substantial tension loads while maintaining the split-resistant nailing pattern that makes field installation reliable.

Simpson MST and HST Strap Ties address specific structural needs - MST models for floor-to-floor tension connections and HST ties for heavy girder-to-pile connections where concentrated loads demand maximum strength.

Specialized Connection Hardware

Simpson Twist Straps (LTS, MTS, HTS Series) create tension connections between wood members with built-in offset capability. The LTS and MTS feature 2-inch bend sections, while HTS models provide 3-3/4-inch bends for greater clearance. These are particularly useful for connecting rafters to plates where space constraints require the offset configuration.

Simpson T and L Strap Ties handle beam-to-column connections with their versatile configurations. The T-strap works for perpendicular connections while the L-strap addresses corner applications.

Heavy Construction Connectors

Simpson Girder Tiedowns (LGT, MGT, VGT, HGT Series) resist uplift forces in multi-ply truss and heavy timber construction. The LGT handles light to moderate loads, while MGT, VGT, and HGT models scale up for high-load structural applications.

Simpson VB Knee Braces provide lateral force resistance when installed at 45 degrees or greater to vertical. With 12-gauge steel and G90 galvanized finish, these connectors offer both strength and corrosion resistance for exposed applications.

Marine and Heavy Timber Applications

Simpson Piling Straps (PS and PSQ Series) create maximum-strength connections between wood girders and piles, particularly important in marine construction and heavy foundation work. These straps perform best when wood members are properly notched for full bearing.

Simpson Stud Plate Ties specifically address stud-to-plate uplift resistance, critical for meeting modern wind load requirements in residential construction.

Mass Timber Solutions

Simpson Mass Timber Column Ties (MCT Series) and Mass Timber Washer Straps (MTWS Series) address the growing mass timber construction market. The MCT provides engineered connections for heavy timber columns, while MTWS straps work with CLT diaphragms and wall systems, offering tested load ratings for these specialized applications.
