A lot of customers come to our website and ask:

Do you have an replaceent  for Sikawrap 230?

It’s a question we hear often—and the answer is a resounding “Yes.” 

For structural reinforcement projects seeking a high-performance, cost-effective, and process-compatible solution, HM23 (manufactured by Shanghai Horse Construction Technology Co., Ltd.) stands out as a trusted direct alternative to SikaWrap® 230.

As a benchmark unidirectional Grade I carbon fiber fabric (CFRP), SikaWrap® 230 has long been a go-to choice for engineers and contractors reinforcing concrete beams, slabs, columns, and piers. However, HM23 has been engineered to meet and exceed the rigorous demands of these projects, offering equivalent mechanical performance, seamless construction compatibility, and significant value advantages. 

Product Positioning and Core Compatibility

SikaWrap® 230 is a unidirectional carbon fiber fabric developed by Sika Group, featuring a basis weight of 230 g/m² and classified as Grade I high-strength CFRP. Its primary application scenarios include flexural, shear, and seismic reinforcement of concrete structures, where it delivers exceptional tensile strength and durability to extend the service life of aging or underperforming buildings and infrastructure.

HM23, belonging to Horse’s HM series of unidirectional carbon fiber fabrics, shares an identical product positioning with SikaWrap® 230. With a basis weight of 230 g/m² and compliance with Grade I high-strength standards, HM23 is specifically engineered for structural reinforcement projects. It perfectly matches SikaWrap® 230 in terms of application scope, target structures, and reinforcement objectives, making it an industry-recognized direct replacement.

Key Performance Parameters Comparison

The following table presents a detailed comparison of core technical parameters between HM23 and SikaWrap® 230, based on nominal values and actual test data, to verify their performance equivalence:

As shown in the table, HM23 achieves perfect alignment with SikaWrap® 230 in critical mechanical properties such as tensile strength, elastic modulus, and elongation at break. 

Advantages of HM23 as a Replacement

1 Performance Equivalence

HM23 is manufactured using high-quality PAN-based carbon fiber and advanced weaving technology, ensuring its mechanical properties are identical to SikaWrap® 230. In actual reinforcement projects, it provides the same level of flexural, shear, and seismic enhancement, effectively improving the load-bearing capacity and durability of structures.

2 Process Compatibility

One of the key advantages of HM23 is its full compatibility with the construction processes of SikaWrap® 230. The recommended construction temperature (5–35℃), required amount of impregnating adhesive, bonding methods (paste/winding), and curing time are completely consistent. This means that construction teams do not need to modify existing construction plans, equipment, or operational procedures when switching to HM23, minimizing disruptions to project schedules.

3 Cost-Effectiveness

Compared to SikaWrap® 230, HM23 offers significant cost advantages without compromising performance. Typically, it is 30%–50% more affordable, making it an ideal choice for large-scale reinforcement projects where cost control is a priority. This cost savings does not come at the expense of quality, as HM23 undergoes strict quality control throughout the production process.

4 Comprehensive Certifications and Reliability

HM23 has obtained a range of international and domestic certifications, including CE, TÜV, and SGS certifications. It is also insured by PICC, providing additional assurance for project quality and safety. These certifications confirm that HM23 meets stringent industry standards, ensuring smooth acceptance by supervisors and regulatory authorities.

5 Stable Supply and Short Lead Times

As a domestically produced product, HM23 benefits from a stable supply chain and short delivery cycles. Unlike imported products that may face delays due to international logistics or customs clearance, HM23 is available in stock in China, enabling quick response to project requirements and reducing the risk of project delays caused by material shortages.

HM23 has proven to be a reliable, high-performance direct replacement for SikaWrap® 230 carbon fiber fabric. With its identical core mechanical properties, full process compatibility, significant cost advantages, and stable supply, HM23 offers an ideal solution for structural reinforcement projects.
