Structural Steel Pipe
Uses for structural steel pipe include sign poles, billboards, bollards, pilings, caissons, scoreboards, water handling, pipe struts, false work, and more. It’s available in various sizes and grades allowing for a broad range of applications.
Steel Casing Pipe (Encasement Pipe)
Used to protect various utility lines (water, gas, electric, etc.) from damage. Casing pipe can be coated or bare depending upon the application and can be manufactured to custom lengths according to requirements.
Steel Pipe Piling
Used when soil or ground conditions are not stable enough to support the weight of the structure being built. Piling comes in various diameters, wall thicknesses, lengths and grades. It can be driven open ended or closed ended.
Caissons / Drilled Shaft Casings
Drilled shaft casings are used when ground conditions require the use of pipe to hold back unstable soils or for water tight applications. Casing is predominately used to drill large diameter drilled shafts and can be installed using drill rigs or casing oscillators. Typically, drilled shaft casings are fabricated with reinforcement bands, twisting slots (“J-Slots”), & CJ2 cutting teeth.
A new structural section developed from fundamental engineering principles. The omega beam is an economical, versatile, twist resistant wide platform that is strong in both directions. Applications include bridges, trestles, docks, wide platform shoring, structural conduits & aqueducts.
Omega Beam Cross Section
A patented new structural section developed from fundamental engineering principles. The omega beam is an economical, versatile, twist resistant wide platform that is strong in both directions. Applications include bridges, trestles, docks, wide platform shoring, structural conduits & aqueducts.
Cold Roll Sheet Pile
Cold Forming is one method of producing sheet pile. These cold formed sheets are usually less expensive for a project by having a wider laying width, less costly method of manufacturing, higher strength to weight ratios and being a time saver with a reduced delivery time from order placement to jobsite.
Hot Roll Sheet Pile
One of the two primary methods of manufacturing sheet piling. It differs mainly from the other by the hot rolling of the interlock which can typically be of the domestic “Ball and Socket” or the import “Larssen” type. This creates an interlock that tends to allow less free motion thus improving its performance in difficult driving conditions and where water flow must be restricted. Due to issue with manufacturing sections produced via Hot Rolling they generally cover the requirements for mid-range to heavy duty application.
Typically less expensive than fabricated corners which can take some time to produce (welded) and are usually available from stock with 24 hour delivery. Specially designed connectors provide easy layouts for corners, “Tees”, combination angle joints as well as convenient splice joints when changing interlock design differences. Once attached to a sheet pile they are easy to drive and extract allowing the contractor to save time by having greater flexibility in the interlock for wall alignment and other corrective measures.
Signs & Scoreboards
No Sign Too Large. No Sign Too Small.
Sign Poles & Sign Supports
Sign Poles can vary in overall height and pipe dimensions ranging from simple one stage sign structures to complex multiple stage sign structures. Trinity Products provides full-service project needs such as: detailed shop drawings, pipe manufacturing, A.I.S.C. certified fabrication, and custom coatings.
Scoreboards require custom fabrication due to the unique nature of their internal construction. Generally fast tracked projects, these structures typically consist of a series of uprights spanning the width of the sign face. The uprights are fabricated from steel pipe or wide flanged beams with a series of catwalks between them providing access to the rear of the sign panel. Trinity Products has participated in some of the most impressive scoreboard structures in the country including: University of Missouri Football, University of Illinois Football, the LA Coliseum, as well as Daytona Speedway and Penn Station.
I - Beams
W (Wide Flange)
The most commonly mentioned I-beam shape for structural applications. The web of the wide flange beam is design to resist shear forces, while the flanges resist most of the bending moment. Wide flange sections are a very efficient form for carrying both bending and shear loads in the plane of the web. They are available in grade ASTM A992 which has generally replaced the order ASTM grades A572 and A36.
Manufactured and designed to transfer structural loads to good bearing soils. They are dimensionally square structural beams that are driven in the ground for deep foundation applications. H-Piles are also used in conjunction with sheet piles to add lateral stiffness and bending resistance where loads exceed the capacity of sheet piles alone.
Street Plates are used to quickly restore a jobsite back to pre-project conditions by bridging open excavations and trenches dug for drainage, cables, gas mains or water mains.
Custom Burned Parts
Trinity Products CNC burn table has the capacity to handle 1/4” to 4” thick plate steel with sizes reaching 10Ft. x 40Ft. Plate shapes can be fully customized to meet the needs of any given project application.
Channel (C-Beam or C-Channel)
Used primarily in building construction and civil engineering. Its cross section consists of a wide “web”, usually but not always oriented vertically, and two “flanges” at the top and bottom of the web, only sticking out on one side of the web. It is distinguished from I-beam or H-beam or W-beam type steel cross sections in that those have flanges on both sides of the web.
Angle (Angle Iron)
A type of structural steel beam used primarily in construction. Its cross section consists of a vertical and horizontal face with consistent thickness that is 90 degrees to one another. It is typically used as a strut for additional structural strength in a larger structure or multiple units can be put together to hold grating for the use of a protective steel wall or walkway.
A type of structural steel beam used primarily in construction. Its cross section consists of a hollow square or rectangle with consistent thickness, but side lengths can vary. Structural tuning can be used as a structural column in lieu of small OD pipe.
A piece of metal, rectangular cross sectioned (flat) and long, but not so wide so as to be called a sheet.
Round Stock (rebar and dowel)
A Rod, a round or square and long piece of metal.
