This EP series covers both the 20-inch and 24-inch nominal diameters in a single product line, with rim widths from 6.00 to 9.00 inches, bolt counts of 6, 8, and 10, and PCD values of 222.25 mm, 275 mm, 285.75 mm, and 335 mm. For a Colombian fleet operator managing multiple truck platforms \u2014 perhaps a mix of older Nu-series heavy trucks alongside more recent Beiben or Sinotruk units \u2014 this means the workshop stockroom can carry a rationalized set of <strong>Tube Type Steel Wheel<\/strong> variants from a single supplier without the complexity and cost of managing multiple vendor relationships.

An SR22 (spherical radius 22 mm) seat lug nut on a rightangle-bored hole creates a line contact that work-hardens and loosens under vibration; using the correct hole profile for the lug nut geometry is essential for maintaining proper clamping force over the service interval. This series is offered with all three principal stud styles found on Asian and European heavy truck platforms operating in Colombia and across South America, eliminating the need to source a custom or modified wheel when replacing a worn original fitment. Fleet purchasing teams in Bogot\u00e1, Medell\u00edn, and Cali who specify <strong>real truck wheels<\/strong> for workshop stock can confirm the correct stud style from the vehicle workshop manual and order accordingly \u2014 no ambiguity, no field modifications.<\/p>\n<\/div>\n<div style=\"width: 100%; max-width: 100%; min-width: 100%; background: linear-gradient(135deg,#e3f2fd,#bbdefb); border-radius: 10px; padding: 24px 28px; box-sizing: border-box; border-top: 4px solid #1976d2; margin-bottom: 16px;\">\n<h3 style=\"color: #1b3a2d; margin: 0 0 12px;\">03 \u2014 High-Tensile Steel for Extended Service Life in Demanding Conditions<\/h3>\n<p style=\"margin: 0;\">The rim and disc components of this <strong>\u0b9f\u0bbf\u0bb0\u0b95\u0bcd \u0b9a\u0b95\u0bcd\u0b95\u0bb0\u0bae\u0bcd<\/strong> series are fabricated from high-strength low-alloy steel with a minimum tensile strength of 590 MPa, achieved through SPFH590 or equivalent DP-grade material. This delivers a fatigue resistance profile significantly higher than ordinary carbon steel tube type wheels, which is particularly relevant for Colombian secondary road conditions where unpaved surfaces, speed bumps, railroad crossings, and pothole impacts generate dynamic load spikes well above the nominal axle load. The high-tensile construction means the rim flange is less likely to deform from kerb strikes during city distribution operations \u2014 a failure mode that creates chronic air-loss problems when the tube valve stem is deflected by flange distortion.

How It Works \u2014 Manufacturing and Assembly of a Tube Type Truck Wheel<\/h2>\n<p style=\"margin: 0 0 18px;\">The production of a reliable <strong>Tube Type Steel Wheel<\/strong> for heavy truck applications begins with material verification at the incoming dock. Each steel coil undergoes X-ray fluorescence (XRF) elemental analysis and tensile coupon testing to confirm that alloy composition and mechanical properties conform to the specification for that order. This step is not a formality \u2014 variability in incoming steel chemistry is one of the root causes of inconsistent wheel fatigue performance in the aftermarket, and the deliberate quality gate at material receipt is what separates a traceable product from an untraceable one. Once material is released, the rim strip is cut to length and fed into the rim-forming line.<\/p>\n<p style=\"margin: 0 0 18px;\">The rim body is formed through a progressive roll-forming process: a flat steel strip is passed through a series of driven forming rolls that progressively shape the material into the complex cross-section of the 20-inch or 24-inch heavy <strong>\u0b9f\u0bbf\u0bb0\u0b95\u0bcd \u0b9a\u0b95\u0bcd\u0b95\u0bb0\u0bae\u0bcd<\/strong> rim profile. For tube type rims, the profile must include a precisely shaped well region that accommodates the folded inner tube during mounting, flanges with a radius and angle controlled to the applicable GB or ISO standard, and bead seats with the correct taper for the tire cross-section. The rim ends are then upset-welded to form a continuous ring, and the weld area is trimmed and expanded to the final diameter tolerance in a separate sizing operation. Any out-of-round or out-of-diameter units are automatically rejected at this stage.<\/p>\n<p style=\"margin: 0 0 18px;\">The disc \u2014 the flat or dished steel component that connects the rim to the axle hub \u2014 is deep-drawn from a steel blank in a multi-stage progressive die set. The bolt holes are punched and then finish-drilled to the specified diameter (26, 27, 32, or 32.5 mm depending on the model) with center-to-center pitch tolerance controlled to \u00b10.2 mm. The stud hole profile \u2014 SR22 spherical, rightangle flat, or 45-degree taper \u2014 is machined as a secondary operation to ensure that the lug nut seating geometry is accurate enough to produce uniform clamping force at the specified truck wheel lug nut torque across all bolt positions. Disc to rim assembly is performed by robotic MIG welding under programmed amperage and travel speed parameters that guarantee full joint penetration. The weld seam is then subjected to a 100% air pressure leak test, after which the assembled <strong>\u0b9f\u0bbf\u0bb0\u0b95\u0bcd \u0b9a\u0b95\u0bcd\u0b95\u0bb0\u0bae\u0bcd<\/strong> moves to the dynamic balance and dimensional inspection station. Units passing all checks proceed to the paint line; units failing any check are quarantined and scrapped.<\/p>\n<p style=\"margin: 0;\">The paint process begins with a mechanical shot blast to Sa 2.5 surface cleanliness, removing all mill scale, weld spatter, and surface contamination before primer application. Epoxy primer is applied electrostatically at 40\u201360 \u00b5m DFT, followed by a polyester or polyurethane topcoat at 60\u201380 \u00b5m. The cured coating withstands \u2265480 hours of neutral salt spray testing \u2014 important assurance for Colombian fleet operators whose <strong>heavy duty truck wheel<\/strong> and tire assemblies must survive the full range of Colombian road environments throughout a multi-year service cycle.<\/p>\n<\/div>\n<p><!-- ===== MATERIAL SECTION ===== --><\/p>\n<div style=\"width: 100%; max-width: 100%; min-width: 100%; padding: 44px 28px; box-sizing: border-box; background: #f4f8f5;\">\n<h2 style=\"color: #1b3a2d; border-left: 5px solid #52b788; padding-left: 14px; margin-bottom: 22px;\">4. \u0baa\u0bca\u0bb0\u0bc1\u0bb3\u0bcd \u0b95\u0bb2\u0bb5\u0bc8<\/h2>\n<p style=\"margin: 0 0 18px;\">The structural performance of any <strong>\u0b9f\u0bbf\u0bb0\u0b95\u0bcd \u0b9a\u0b95\u0bcd\u0b95\u0bb0\u0bae\u0bcd<\/strong> over a 300,000\u2013500,000 km service life is determined first by material choice, then by forming process, and finally by weld quality. This series addresses all three through a disciplined approach to each stage. The rim shell and disc are produced from SPFH590 hot-rolled high-strength steel \u2014 a grade with a minimum yield strength of 440 MPa and ultimate tensile strength of 590\u2013730 MPa. The elevated yield point is what prevents the rim flange from permanently deforming after a pothole impact or kerb strike, which is the most common mode of tube type <strong>\u0b9f\u0bbf\u0bb0\u0b95\u0bcd \u0b9a\u0b95\u0bcd\u0b95\u0bb0\u0bae\u0bcd<\/strong> service damage on Colombia&#8217;s secondary and tertiary road network. The 18% minimum elongation at fracture is what gives the material enough ductility to survive the deep-drawing operations required to form the disc profile without developing forming cracks at tight-radius features around the bolt hole annulus.<\/p>\n<p style=\"margin: 0 0 18px;\">For specific models in the series where mass reduction is a priority \u2014 particularly for vehicles operating near their legal Colombian gross vehicle weight limit under Resoluci\u00f3n 4100 de 2004 \u2014 DP600 dual-phase steel is used in the disc pressing. DP600&#8217;s dual-phase microstructure (hard martensite islands in a soft ferrite matrix) gives it a higher specific strength than conventional carbon steel, allowing a slightly thinner disc section to carry the same cyclic load. The net effect on a typical <strong>heavy duty truck wheel<\/strong> is a mass reduction of 10\u201315% per disc compared to a standard carbon steel equivalent \u2014 directly beneficial to payload capacity on the axle positions where this <strong>\u0b9f\u0bbf\u0bb0\u0b95\u0bcd \u0b9a\u0b95\u0bcd\u0b95\u0bb0\u0bae\u0bcd<\/strong> is mounted.

Shot blasting to Sa 2.5 (ISO 8501-1) creates a surface cleanliness and profile that maximizes epoxy primer adhesion. The primer and topcoat system cures to a total DFT of 100\u2013140 \u00b5m, providing a durable corrosion barrier that has been validated to ISO 9227 neutral salt spray test protocol for \u2265480 hours before corrosion breakthrough \u2014 a standard that reflects realistic long-term fleet service conditions rather than just factory-exit condition.<\/p>\n<\/div>\n<p><!-- ===== APPLICATION SCENARIOS ===== --><\/p>\n<div style=\"width: 100%; max-width: 100%; min-width: 100%; padding: 44px 28px; box-sizing: border-box; background: #ffffff;\">\n<h2 style=\"color: #1b3a2d; border-left: 5px solid #52b788; padding-left: 14px; margin-bottom: 28px;\">5. \u0baa\u0baf\u0ba9\u0bcd\u0baa\u0bbe\u0b9f\u0bcd\u0b9f\u0bc1\u0b9a\u0bcd \u0b9a\u0bc2\u0bb4\u0bcd\u0ba8\u0bbf\u0bb2\u0bc8\u0b95\u0bb3\u0bcd<\/h2>\n<div style=\"width: 100%; max-width: 100%; min-width: 100%; background: #f4f8f5; border-radius: 10px; padding: 24px 28px; box-sizing: border-box; border-left: 5px solid #2d6a4f; margin-bottom: 16px;\">\n<h3 style=\"color: #1b3a2d; margin: 0 0 12px;\">Long-Distance Freight \u2014 National Road Network, Colombia<\/h3>\n<p style=\"margin: 0;\">The 7.50V-20 and 8.00V-20 variants of this <strong>\u0b9f\u0bbf\u0bb0\u0b95\u0bcd \u0b9a\u0b95\u0bcd\u0b95\u0bb0\u0bae\u0bcd<\/strong> series are the most widely applicable for long-haul freight trucks operating on Colombia&#8217;s primary national routes \u2014 the Ruta del Sol corridor (Bogot\u00e1\u2013Barranquilla), the Bogot\u00e1\u2013Buenaventura route through the Western Cordillera, and the Medell\u00edn\u2013Bogot\u00e1 highway. These routes involve sustained highway operation at legal maximum GVW, combined with demanding gradient work through the Andes where brake thermal management and wheel structural integrity under downhill braking loads are critical. The high-tensile steel construction and full-penetration weld standard of this series provide the structural margin needed for sustained heavy-load operations, while the broad tire compatibility range (9.00-20 through 11.00-20) covers the cross-ply and radial tire combinations used on the Foton, CNHTC Howo, and Beiben platforms that dominate this segment of the Colombian freight market.<\/p>\n<\/div>\n<div style=\"width: 100%; max-width: 100%; min-width: 100%; background: #f4f8f5; border-radius: 10px; padding: 24px 28px; box-sizing: border-box; border-left: 5px solid #f59e0b; margin-bottom: 16px;\">\n<h3 style=\"color: #1b3a2d; margin: 0 0 12px;\">Agricultural and Mining Haulage<\/h3>\n<p style=\"margin: 0;\">The 8.5-20 (45\u00b0 stud, 12.00-20 tire) and 9.0-20 (rightangle, 12.00-20 tire) configurations are purpose-appropriate for agricultural haulage trucks and light mining support vehicles in Colombia&#8217;s coffee, palm oil, and mineral extraction sectors.
